Misc. Notes

This NIEF attribute is meant to be flexible enough to support protocol-specific implementations of the concept of a unique subject or user identifier across multiple protocols. When implementing support for this attribute within a protocol that natively supports the unique subject identifier concept, implementers should adhere to any additional constraints and requirements imposed by that protocol. Implementers may wish to review the SAML Subject Id Attribute specification: http://docs.oasis-open.org/security/saml-subject-id-attr/v1.0/csprd02/saml-subject-id-attr-v1.0-csprd02.html

This attribute is intended to supersede the FederationId attribute defined by GFIPM: https://nief.org/attribute-registry/attributes/user/gfipm/FederationId/2.0/
