+The ecosystem provided in this specification is in contrast to a typical

+and managing identity information for [=holders=], while providing
+authentication services to [=relying party=] applications within a federation or
+distributed network. In a federated identity model, the [=holder=] is tightly
+bound to the identity provider. This specification does not use the "identity
+provider", "federated identity", or "relying party" terminology unless comparing
+or mapping the concepts in this document to other specifications. This
+specification decouples the identity provider concept into two distinct
+concepts: the [=issuer=] and the [=holder=].
