context: This clause describes the GAA and ID-FF / SAML v2.0 / ID-WSF architecture. The GAA system consists of UE, BSF, NAF, and HSS (and Zn-Proxy dependent on configuration) as described in TS 33.220 [1]. In the Liberty Alliance architecture the following system entities exist: Principal (shown as UE in the figures), IdP, DS, SP, and the roles WSC, and WSP. Typical Liberty Alliance network models are shown for ID-FF in Figure 4.2.-1 and for ID-WSF in 4.2.-2. As SAML v2.0 [28] was specified with ID-FF 1.2 taken as an input, SAML v2.0 is a superset of ID-FF 1.2 and SAML v1.1 with some relatively small differences (mostly extensions). The related system entities are: UA, SP and IdP (User Agent, Service Provider and Identity Provider, respectively). For this strong similarity, no separate discussion on SAML v2.0 is given in this section unless necessary. However, as SAML v2.0 has formally superseded ID-FF 1.2, it is recommended that the solutions implementing the interworking functionality
description: Security Assertion Markup Language (SAML) is a protocol used for exchanging authentication and authorization data between systems. It provides a framework for asserting identities and permissions in a secure manner, enabling single sign-on (SSO) capabilities across different domains.
explanation: The text explicitly states that SAML v2.0 is a protocol,  and describes its function as exchanging authentication and authorization data.
