`presentation_definition.input_descriptors.constraints.limit_disclosure`|`preferred` or `required` as defined in [the spec](https://identity.foundation/presentation-exchange/#input-descriptor-object) and as supported by the Holder and Verifier proof mechanisms.
Note that the Holder MUST have credentials with cryptographic proof suites that are capable of selective disclosure in order to respond to a request with `limit_disclosure: "required"`.
See [RFC0593](../0593-json-ld-cred-attach/README.md) for appropriate crypto suites.

Note that this feature allows the Holder to present credentials with a different subject identifier than the DID used to establish the DIDComm connection with the Verifier.
