Implement a did_doc! macro that allows to define a DID Document in a fluent manner:

did_doc!({
  "@context": ["https://www.w3.org/2019/did/v1", "https://w3id.org/security/v1"],
  "id": "did:example:123456789abcdefghi",
  "publicKey": [{
    "id": "did:example:123456789abcdefghi#keys-1",
    "type": "RsaVerificationKey2018",
    "controller": "did:example:123456789abcdefghi",
    "publicKeyPem": "-----BEGIN PUBLIC KEY...END PUBLIC KEY-----\r\n"
  }, {
    "id": "did:example:123456789abcdefghi#keys-2",
    "type": "Ed25519VerificationKey2018",
    "controller": "did:example:pqrstuvwxyz0987654321",
    "publicKeyBase58": "H3C2AVvLMv6gmMNam3uVAjZpfkcJCwDwnZn6z3wXmqPV"
  }, {
    "id": "did:example:123456789abcdefghi#keys-3",
    "type": "Secp256k1VerificationKey2018",
    "controller": "did:example:123456789abcdefghi",
    "publicKeyHex": "02b97c30de767f084ce3080168ee293053ba33b235d7116a3263d29f1450936b71"
  }],
})

Note: ":" token might have to be replaced by "=>" token (see https://github.com/maciejhirsz/json-rust)

Implementers builder pattern for DID & DIDDocument structs for a nicer API + prevent external modification via the pub members.

Support for percent encoding syntax in DIDParam following W3C spec at : https://w3c-ccg.github.io/did-spec/#generic-did-parameter-names
Generic DID syntax defined at : https://w3c-ccg.github.io/did-spec/#decentralized-identifiers-dids

Support for a list of Service endpoints in a DID Document following the W3C spec at : https://w3c-ccg.github.io/did-spec/#service-endpoints

Implement a DID::is_valid -> bool func to verify a DID string w/o parsing it into a DID struct

Add support for Path syntax in DID following W3C spec at : https://w3c-ccg.github.io/did-spec/#path

Implement data structure & parser for DID Document, see spec : https://w3c-ccg.github.io/did-spec/#did-documents
Existing Typescript implementation here: https://github.com/decentralized-identity/did-common-typescript

Support for Fragment syntax in DID string following W3C spec at : https://w3c-ccg.github.io/did-spec/#fragment

Support for an Updated timestamp in a DID Document following the W3C spec at : https://w3c-ccg.github.io/did-spec/#updated-optional

The library should support compilation to no_std environment for use in a Wasm context e.g. as a dependency in a Substrate runtime module.

Support for a list of Authentication verification methods in a DID Document following the W3C spec at : https://w3c-ccg.github.io/did-spec/#authentication

Support for a Creation timestamp in a DID Document following the W3C spec at : https://w3c-ccg.github.io/did-spec/#created-optional

Implement a pluggable resolver model with a "driver" per chain.
There should probably be a DIDResolver trait defined a fetch function returning a DIDDocument containing the metadata associated with the DID passed in parameter.
See existing implementation in Typescript: https://github.com/decentralized-identity/did-common-typescript

Support for Query syntax in DID string following W3C spec at : https://w3c-ccg.github.io/did-spec/#query

Support for a Proof of integrity in a DID Document following the W3C spec at : https://w3c-ccg.github.io/did-spec/#proof-optional
