-- `data_model_versions_supported` - Required. List of strings indicating the supported VC Data Model versions. The list MUST contain at least one value. The values MUST be a valid data model version. Current supported values include `1.1` and `2.0`.
-- `binding_required` - Optional. Boolean indicating whether the credential MUST be bound to the holder. If omitted, the credential is not required to be bound to the holder. If set to `true`, the credential MUST be bound to the holder using at least one of the binding methods defined in `binding_method`.
-- `binding_method` - Required if `binding_required` is true. Object containing key-value pairs of binding methods supported by the issuer to bind the credential to a holder. If the value is omitted, this indicates the issuer does not support any binding methods for issuance of the credential. See [Binding Methods](#binding-methods) for a registry of default binding methods supported as part of this RFC.
+- `binding_method` - Optional. Object containing key-value pairs of binding methods supported by the issuer to bind the credential to a holder. If the value is omitted, this indicates the issuer does not support any binding methods for issuance of the credential. See [Binding Methods](#binding-methods) for a registry of default binding methods supported as part of this RFC.
 - `credential` - Required. The credential to be issued. The credential MUST be compliant with the **first** `data_model_versions_supported` entry version of VC Data Model, except for the omission of a set required keys that may only be known at the time of issuance. See [Credential Offer Exceptions](#credential-offer-exceptions) for a list of exceptions. The credential MUST NOT contain any proofs. Some properties MAY be omitted if they will only be available at time of issuance, such as `issuanceDate`, `issuer`, `credentialSubject.id`, `credentialStatus`, `credentialStatus.id`.
