credential extensions under credential subject

https://w3c.github.io/vc-overview/#base_example_jwt_unencoded

credentialSchema as a property of credential subject, instead of a top level property:

{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://www.example.org/vocabs/alumni"
  ],
  "id": "https://university.example/Credential123",
  "type": ["VerifiableCredential", "ExampleAlumniCredential"],
  "issuer": "did:example:2g55q912ec3476eba2l9812ecbfe",
  "validFrom": "2010-01-01T00:00:00Z",
  "credentialSubject": {
    "id": "https://www.example.org/persons/pat",
    "name": "Pat",
    "alumniOf": {
      "id": "did:example:c276e12ec21ebfeb1f712ebc6f1",

    "credentialSchema": {
