+
+
+see examples in [godoc](https://pkg.go.dev/github.com/santhosh-tekuri/jsonschema/v5)
+
+The schema is compiled against the version specified in `$schema` property.
+If "$schema" property is missing, it uses latest draft which currently implemented
+by this library.
+
+You can force to use specific version, when `$schema` is missing, as follows:
+
+```go
+compiler := jsonschema.NewCompiler()
+compiler.Draft = jsonschema.Draft4
+```
+
+This package supports loading json-schema from filePath and fileURL.
+
+To load json-schema from HTTPURL, add following import:
+
+```go
+import _ "github.com/santhosh-tekuri/jsonschema/v5/httploader"
+```
+
+## Rich Errors
+
+The ValidationError returned by Validate method contains detailed context to understand why and where the error is.
+
+schema.json:
+```json
+{
+      "$ref": "t.json#/definitions/employee"
+}
+```
+
+t.json:
+```json
+{
+    "definitions": {
+        "employee": {
+            "type": "string"
+        }
+    }
+}
+```
+
+doc.json:
+```json
+1
+```
+
+assuming `err` is the ValidationError returned when `doc.json` validated with `schema.json`,
+```go
+fmt.Printf("%#v\n", err) // using %#v prints errors hierarchy
+```
+Prints:
+```
+[I#] [S#] doesn't validate with file:///Users/santhosh/jsonschema/schema.json#
+  [I#] [S#/$ref] doesn't validate with 'file:///Users/santhosh/jsonschema/t.json#/definitions/employee'
+    [I#] [S#/definitions/employee/type] expected string, but got number
+```
+
+Here `I` stands for instance document and `S` stands for schema document.  
+The json-fragments that caused error in instance and schema documents are represented using json-pointer notation.  
+Nested causes are printed with indent.
+
+To output `err` in `flag` output format:
+```go
+b, _ := json.MarshalIndent(err.FlagOutput(), "", "  ")
+fmt.Println(string(b))
+```
+Prints:
+```json
+{
+  "valid": false
+}
+```
+To output `err` in `basic` output format:
+```go
+b, _ := json.MarshalIndent(err.BasicOutput(), "", "  ")
+fmt.Println(string(b))
+```
+Prints:
+```json
+{
+  "valid": false,
+  "errors": [
+    {
+      "keywordLocation": "",
+      "absoluteKeywordLocation": "file:///Users/santhosh/jsonschema/schema.json#",
+      "instanceLocation": "",
+      "error": "doesn't validate with file:///Users/santhosh/jsonschema/schema.json#"
+    },
+    {
+      "keywordLocation": "/$ref",
+      "absoluteKeywordLocation": "file:///Users/santhosh/jsonschema/schema.json#/$ref",
+      "instanceLocation": "",
+      "error": "doesn't validate with 'file:///Users/santhosh/jsonschema/t.json#/definitions/employee'"
+    },
+    {
+      "keywordLocation": "/$ref/type",
+      "absoluteKeywordLocation": "file:///Users/santhosh/jsonschema/t.json#/definitions/employee/type",
+      "instanceLocation": "",
+      "error": "expected string, but got number"
+    }
+  ]
+}
+```
+To output `err` in `detailed` output format:
+```go
+b, _ := json.MarshalIndent(err.DetailedOutput(), "", "  ")
+fmt.Println(string(b))
+```
+Prints:
+```json
+{
+  "valid": false,
+  "keywordLocation": "",
+  "absoluteKeywordLocation": "file:///Users/santhosh/jsonschema/schema.json#",
+  "instanceLocation": "",
+  "errors": [
+    {
+      "valid": false,
+      "keywordLocation": "/$ref",
+      "absoluteKeywordLocation": "file:///Users/santhosh/jsonschema/schema.json#/$ref",
+      "instanceLocation": "",
+      "errors": [
+        {
+          "valid": false,
+          "keywordLocation": "/$ref/type",
+          "absoluteKeywordLocation": "file:///Users/santhosh/jsonschema/t.json#/definitions/employee/type",
+          "instanceLocation": "",
+          "error": "expected string, but got number"
+        }
+      ]
+    }
+  ]
+}
+```
+
+## CLI
+
+to install `go install github.com/santhosh-tekuri/jsonschema/cmd/jv@latest`
+
+```bash
+jv [-draft INT] [-output FORMAT] [-assertformat] [-assertcontent] <json-schema> [<json-or-yaml-doc>]...
+  -assertcontent
+    	enable content assertions with draft >= 2019
+  -assertformat
+    	enable format assertions with draft >= 2019
+  -draft int
+    	draft used when '$schema' attribute is missing. valid values 4, 5, 7, 2019, 2020 (default 2020)
+  -output string
+    	output format. valid values flag, basic, detailed
+```
+
+if no `<json-or-yaml-doc>` arguments are passed, it simply validates the `<json-schema>`.  
+if `$schema` attribute is missing in schema, it uses latest version. this can be overridden by passing `-draft` flag
+
+exit-code is 1, if there are any validation errors
+
+`jv` can also validate yaml files. It also accepts schema from yaml files.
+
+## Validating YAML Documents
+
+since yaml supports non-string keys, such yaml documents are rendered as invalid json documents.  
+
+most yaml parser use `map[interface{}]interface{}` for object,  
+whereas json parser uses `map[string]interface{}`.  
+
+so we need to manually convert them to `map[string]interface{}`.   
+below code shows such conversion by `toStringKeys` function.
+
+https://play.golang.org/p/Hhax3MrtD8r
+
+NOTE: if you are using `gopkg.in/yaml.v3`, then you do not need such conversion. since this library
+returns `map[string]interface{}` if all keys are strings.

+Package jsonschema provides json-schema compilation and validation.
+
+Features:
+  - implements draft 2020-12, 2019-09, draft-7, draft-6, draft-4
+  - fully compliant with JSON-Schema-Test-Suite, (excluding some optional)
+  - list of optional tests that are excluded can be found in schema_test.go(variable skipTests)
+  - validates schemas against meta-schema
+  - full support of remote references
+  - support of recursive references between schemas
+  - detects infinite loop in schemas
+  - thread safe validation
+  - rich, intuitive hierarchial error messages with json-pointers to exact location
+  - supports output formats flag, basic and detailed
+  - supports enabling format and content Assertions in draft2019-09 or above
+  - change Compiler.AssertFormat, Compiler.AssertContent to true
+  - compiled schema can be introspected. easier to develop tools like generating go structs given schema
+  - supports user-defined keywords via extensions
+  - implements following formats (supports user-defined)
+  - date-time, date, time, duration (supports leap-second)
+  - uuid, hostname, email
+  - ip-address, ipv4, ipv6
+  - uri, uriref, uri-template(limited validation)
+  - json-pointer, relative-json-pointer
+  - regex, format
+  - implements following contentEncoding (supports user-defined)
+  - base64
+  - implements following contentMediaType (supports user-defined)
+  - application/json
+  - can load from files/http/https/string/[]byte/io.Reader (supports user-defined)
+
+The schema is compiled against the version specified in "$schema" property.
+If "$schema" property is missing, it uses latest draft which currently implemented
+by this library.
+
+You can force to use specific draft,  when "$schema" is missing, as follows:
+
+	compiler := jsonschema.NewCompiler()
+	compiler.Draft = jsonschema.Draft4
+
+This package supports loading json-schema from filePath and fileURL.
+
+To load json-schema from HTTPURL, add following import:
+
+	import _ "github.com/santhosh-tekuri/jsonschema/v5/httploader"
+
+you can validate yaml documents. see https://play.golang.org/p/sJy1qY7dXgA

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You

-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-    if err != nil {
-        panic(err.Error())
-    }
-
-    if result.Valid() {
-        fmt.Printf("The document is valid\n")
-    } else {
-        fmt.Printf("The document is not valid. see errors :\n")
-        for _, desc := range result.Errors() {
-            fmt.Printf("- %s\n", desc)
-        }
-    }
-}
-
-
-```
-
-#### Loaders
-
-There are various ways to load your JSON data.
-In order to load your schemas and documents,
-first declare an appropriate loader :
-
-* Web / HTTP, using a reference :
-
-```go
-loader := gojsonschema.NewReferenceLoader("http://www.some_host.com/schema.json")
-```
-
-* Local file, using a reference :
-
-```go
-loader := gojsonschema.NewReferenceLoader("file:///home/me/schema.json")
-```
-
-References use the URI scheme, the prefix (file://) and a full path to the file are required.
-
-* JSON strings :
-
-```go
-loader := gojsonschema.NewStringLoader(`{"type": "string"}`)
-```
-
-* Custom Go types :
-
-```go
-m := map[string]interface{}{"type": "string"}
-loader := gojsonschema.NewGoLoader(m)
-```
-
-And
-
-```go
-type Root struct {
-	Users []User `json:"users"`
-}
-
-type User struct {
-	Name string `json:"name"`
-}
-
-...
-
-data := Root{}
-data.Users = append(data.Users, User{"John"})
-data.Users = append(data.Users, User{"Sophia"})
-data.Users = append(data.Users, User{"Bill"})
-
-loader := gojsonschema.NewGoLoader(data)
-```
-
-#### Validation
-
-Once the loaders are set, validation is easy :
-
-```go
-result, err := gojsonschema.Validate(schemaLoader, documentLoader)
-```
-
-Alternatively, you might want to load a schema only once and process to multiple validations :
-
-```go
-schema, err := gojsonschema.NewSchema(schemaLoader)
-...
-result1, err := schema.Validate(documentLoader1)
-...
-result2, err := schema.Validate(documentLoader2)
-...
-// etc ...
-```
-
-To check the result :
-
-```go
-    if result.Valid() {
-    	fmt.Printf("The document is valid\n")
-    } else {
-        fmt.Printf("The document is not valid. see errors :\n")
-        for _, err := range result.Errors() {
-        	// Err implements the ResultError interface
-            fmt.Printf("- %s\n", err)
-        }
-    }
-```
-
-
-## Loading local schemas
-
-By default `file` and `http(s)` references to external schemas are loaded automatically via the file system or via http(s). An external schema can also be loaded using a `SchemaLoader`.
-
-```go
-	sl := gojsonschema.NewSchemaLoader()
-	loader1 := gojsonschema.NewStringLoader(`{ "type" : "string" }`)
-	err := sl.AddSchema("http://some_host.com/string.json", loader1)
-```
-
-Alternatively if your schema already has an `$id` you can use the `AddSchemas` function
-```go
-	loader2 := gojsonschema.NewStringLoader(`{
-			"$id" : "http://some_host.com/maxlength.json",
-			"maxLength" : 5
-		}`)
-	err = sl.AddSchemas(loader2)
-```
-
-The main schema should be passed to the `Compile` function. This main schema can then directly reference the added schemas without needing to download them.
-```go
-	loader3 := gojsonschema.NewStringLoader(`{
-		"$id" : "http://some_host.com/main.json",
-		"allOf" : [
-			{ "$ref" : "http://some_host.com/string.json" },
-			{ "$ref" : "http://some_host.com/maxlength.json" }
-		]
-	}`)
-
-	schema, err := sl.Compile(loader3)
-
-	documentLoader := gojsonschema.NewStringLoader(`"hello world"`)
-
-	result, err := schema.Validate(documentLoader)
-```
-
-It's also possible to pass a `ReferenceLoader` to the `Compile` function that references a loaded schema.
-
-```go
-err = sl.AddSchemas(loader3)
-schema, err := sl.Compile(gojsonschema.NewReferenceLoader("http://some_host.com/main.json"))
-``` 
-
-Schemas added by `AddSchema` and `AddSchemas` are only validated when the entire schema is compiled, unless meta-schema validation is used.
-
-## Using a specific draft
-By default `gojsonschema` will try to detect the draft of a schema by using the `$schema` keyword and parse it in a strict draft-04, draft-06 or draft-07 mode. If `$schema` is missing, or the draft version is not explicitely set, a hybrid mode is used which merges together functionality of all drafts into one mode.
-
-Autodectection can be turned off with the `AutoDetect` property. Specific draft versions can be specified with the `Draft` property.
-
-```go
-sl := gojsonschema.NewSchemaLoader()
-sl.Draft = gojsonschema.Draft7
-sl.AutoDetect = false
-```
-
-If autodetection is on (default), a draft-07 schema can savely reference draft-04 schemas and vice-versa, as long as `$schema` is specified in all schemas.
-
-## Meta-schema validation
-Schemas that are added using the `AddSchema`, `AddSchemas` and `Compile` can be validated against their meta-schema by setting the `Validate` property.
-
-The following example will produce an error as `multipleOf` must be a number. If `Validate` is off (default), this error is only returned at the `Compile` step. 
-
-```go
-sl := gojsonschema.NewSchemaLoader()
-sl.Validate = true
-err := sl.AddSchemas(gojsonschema.NewStringLoader(`{
-     $id" : "http://some_host.com/invalid.json",
-    "$schema": "http://json-schema.org/draft-07/schema#",
-    "multipleOf" : true
-}`))
- ```
-``` 
- ```
-
-Errors returned by meta-schema validation are more readable and contain more information, which helps significantly if you are developing a schema.
-
-Meta-schema validation also works with a custom `$schema`. In case `$schema` is missing, or `AutoDetect` is set to `false`, the meta-schema of the used draft is used.
-
-
-## Working with Errors
-
-The library handles string error codes which you can customize by creating your own gojsonschema.locale and setting it
-```go
-gojsonschema.Locale = YourCustomLocale{}
-```
-
-However, each error contains additional contextual information. 
-
-Newer versions of `gojsonschema` may have new additional errors, so code that uses a custom locale will need to be updated when this happens.
-
-**err.Type()**: *string* Returns the "type" of error that occurred. Note you can also type check. See below
-
-Note: An error of RequiredType has an err.Type() return value of "required"
-
-    "required": RequiredError
-    "invalid_type": InvalidTypeError
-    "number_any_of": NumberAnyOfError
-    "number_one_of": NumberOneOfError
-    "number_all_of": NumberAllOfError
-    "number_not": NumberNotError
-    "missing_dependency": MissingDependencyError
-    "internal": InternalError
-    "const": ConstEror
-    "enum": EnumError
-    "array_no_additional_items": ArrayNoAdditionalItemsError
-    "array_min_items": ArrayMinItemsError
-    "array_max_items": ArrayMaxItemsError
-    "unique": ItemsMustBeUniqueError
-    "contains" : ArrayContainsError
-    "array_min_properties": ArrayMinPropertiesError
-    "array_max_properties": ArrayMaxPropertiesError
-    "additional_property_not_allowed": AdditionalPropertyNotAllowedError
-    "invalid_property_pattern": InvalidPropertyPatternError
-    "invalid_property_name":  InvalidPropertyNameError
-    "string_gte": StringLengthGTEError
-    "string_lte": StringLengthLTEError
-    "pattern": DoesNotMatchPatternError
-    "multiple_of": MultipleOfError
-    "number_gte": NumberGTEError
-    "number_gt": NumberGTError
-    "number_lte": NumberLTEError
-    "number_lt": NumberLTError
-    "condition_then" : ConditionThenError
-    "condition_else" : ConditionElseError
-
-**err.Value()**: *interface{}* Returns the value given
-
-**err.Context()**: *gojsonschema.JsonContext* Returns the context. This has a String() method that will print something like this: (root).firstName
-
-**err.Field()**: *string* Returns the fieldname in the format firstName, or for embedded properties, person.firstName. This returns the same as the String() method on *err.Context()* but removes the (root). prefix.
-
-**err.Description()**: *string* The error description. This is based on the locale you are using. See the beginning of this section for overwriting the locale with a custom implementation.
-
-**err.DescriptionFormat()**: *string* The error description format. This is relevant if you are adding custom validation errors afterwards to the result.
-
-**err.Details()**: *gojsonschema.ErrorDetails* Returns a map[string]interface{} of additional error details specific to the error. For example, GTE errors will have a "min" value, LTE will have a "max" value. See errors.go for a full description of all the error details. Every error always contains a "field" key that holds the value of *err.Field()*
-
-Note in most cases, the err.Details() will be used to generate replacement strings in your locales, and not used directly. These strings follow the text/template format i.e.
-```
-{{.field}} must be greater than or equal to {{.min}}
-```
-
-The library allows you to specify custom template functions, should you require more complex error message handling.
-```go
-gojsonschema.ErrorTemplateFuncs = map[string]interface{}{
-	"allcaps": func(s string) string {
-		return strings.ToUpper(s)
-	},
-}
-```
-
-Given the above definition, you can use the custom function `"allcaps"` in your localization templates:
-```
-{{allcaps .field}} must be greater than or equal to {{.min}}
-```
-
-The above error message would then be rendered with the `field` value in capital letters. For example:
-```
-"PASSWORD must be greater than or equal to 8"
-```
-
-Learn more about what types of template functions you can use in `ErrorTemplateFuncs` by referring to Go's [text/template FuncMap](https://golang.org/pkg/text/template/#FuncMap) type.
-
-## Formats
-JSON Schema allows for optional "format" property to validate instances against well-known formats. gojsonschema ships with all of the formats defined in the spec that you can use like this:
-
-````json
-{"type": "string", "format": "email"}
-````
-
-Not all formats defined in draft-07 are available. Implemented formats are:
-
-* `date`
-* `time`
-* `date-time`
-* `hostname`. Subdomains that start with a number are also supported, but this means that it doesn't strictly follow [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5) and has the implication that ipv4 addresses are also recognized as valid hostnames.
-* `email`. Go's email parser deviates slightly from [RFC5322](https://tools.ietf.org/html/rfc5322). Includes unicode support.
-* `idn-email`. Same caveat as `email`.
-* `ipv4`
-* `ipv6`
-* `uri`. Includes unicode support.
-* `uri-reference`. Includes unicode support.
-* `iri`
-* `iri-reference`
-* `uri-template`
-* `uuid`
-* `regex`. Go uses the [RE2](https://github.com/google/re2/wiki/Syntax) engine and is not [ECMA262](http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf) compatible.
-* `json-pointer`
-* `relative-json-pointer`
-
-`email`, `uri` and `uri-reference` use the same validation code as their unicode counterparts `idn-email`, `iri` and `iri-reference`. If you rely on unicode support you should use the specific 
-unicode enabled formats for the sake of interoperability as other implementations might not support unicode in the regular formats.
-
-The validation code for `uri`, `idn-email` and their relatives use mostly standard library code.
-
-For repetitive or more complex formats, you can create custom format checkers and add them to gojsonschema like this:
-
-```go
-// Define the format checker
-type RoleFormatChecker struct {}
-
-// Ensure it meets the gojsonschema.FormatChecker interface
-func (f RoleFormatChecker) IsFormat(input interface{}) bool {
-
-    asString, ok := input.(string)
-    if ok == false {
-        return false
-    }
-
-    return strings.HasPrefix("ROLE_", asString)
-}
-
-// Add it to the library
-gojsonschema.FormatCheckers.Add("role", RoleFormatChecker{})
-````
-
-Now to use in your json schema:
-````json
-{"type": "string", "format": "role"}
-````
-
-Another example would be to check if the provided integer matches an id on database:
-
-JSON schema:
-```json
-{"type": "integer", "format": "ValidUserId"}
-```
-
-```go
-// Define the format checker
-type ValidUserIdFormatChecker struct {}
-
-// Ensure it meets the gojsonschema.FormatChecker interface
-func (f ValidUserIdFormatChecker) IsFormat(input interface{}) bool {
-
-    asFloat64, ok := input.(float64) // Numbers are always float64 here
-    if ok == false {
-        return false
-    }
-
-    // XXX
-    // do the magic on the database looking for the int(asFloat64)
-
-    return true
-}
-
-// Add it to the library
-gojsonschema.FormatCheckers.Add("ValidUserId", ValidUserIdFormatChecker{})
-````
-
-Formats can also be removed, for example if you want to override one of the formats that is defined by default.
-
-```go
-gojsonschema.FormatCheckers.Remove("hostname")
-```
-
-
-## Additional custom validation
-After the validation has run and you have the results, you may add additional
-errors using `Result.AddError`. This is useful to maintain the same format within the resultset instead
-of having to add special exceptions for your own errors. Below is an example.
-
-```go
-type AnswerInvalidError struct {
-    gojsonschema.ResultErrorFields
-}
-
-func newAnswerInvalidError(context *gojsonschema.JsonContext, value interface{}, details gojsonschema.ErrorDetails) *AnswerInvalidError {
-    err := AnswerInvalidError{}
-    err.SetContext(context)
-    err.SetType("custom_invalid_error")
-    // it is important to use SetDescriptionFormat() as this is used to call SetDescription() after it has been parsed
-    // using the description of err will be overridden by this.
-    err.SetDescriptionFormat("Answer to the Ultimate Question of Life, the Universe, and Everything is {{.answer}}")
-    err.SetValue(value)
-    err.SetDetails(details)
-
-    return &err
-}
-
-func main() {
-    // ...
-    schema, err := gojsonschema.NewSchema(schemaLoader)
-    result, err := gojsonschema.Validate(schemaLoader, documentLoader)
-
-    if true { // some validation
-        jsonContext := gojsonschema.NewJsonContext("question", nil)
-        errDetail := gojsonschema.ErrorDetails{
-            "answer": 42,
-        }
-        result.AddError(
-            newAnswerInvalidError(
-                gojsonschema.NewJsonContext("answer", jsonContext),
-                52,
-                errDetail,
-            ),
-            errDetail,
-        )
-    }
-
-    return result, err
-
-}
-```
-
-This is especially useful if you want to add validation beyond what the
-json schema drafts can provide such business specific logic.
