Example 16 shows a JSON Schema using the allOf property to combine a verifiable credential schema, a name schema, and an email schema. Example 17 shows a verifiable credential that the combined schema validates, with credentialSubject containing firstName, lastName, and emailAddress.

```json

### JsonSchemaCredential Example with Embedded JSON Schema

Source: https://www.w3.org/TR/vc-json-schema

Example 4: Example Email Credential Schema. This JSON-LD verifiable credential uses the JsonSchemaCredential type and embeds a JSON Schema (draft 2020-12) in the credentialSubject.jsonSchema property. The credentialSchema references the W3C JSON Schema v2 and includes a digestSRI for integrity.

```json
{
  "@context": [
      "https://www.w3.org/ns/credentials/v2",
      "https://www.w3.org/ns/credentials/examples/v2"
  ],

    }
  }
