HTTP POST and HTTP Redirect are mandatory to implement. HTTP Artifact is OPTIONAL. - Section 2.4 (TLS Usage) is completely new. Paragraph at lines 334--340 is new, otherwise this section is a reformulation of the TLS requirements previously scattered about (or implied). - Section 2.5 (Choice of Binding) is completely new. Suggests SimpleSign may be used, otherwise there's nothing new here. - Aside: Is SimpleSign allowed? Does it make sense to use SimpleSign in a profile meant to be "stronger" than ordinary Web Browser SSO? If SimpleSign is allowed, then language using the words "sign" or "signing" needs to be loosened. - Section 2.7.1 (<samlp:AuthnRequest> Usage). The request may be signed (period). New requirements regarding the XML attributes on the <samlp:AuthnRequest> element. Removed the redundant requirement re AllowCreate="true". - Section 2.7.2 (<samlp:AuthnRequest> Message Processing Rules). New rules in the case where the request is signed. Clarification of behavior if the XML attributes on the <samlp:AuthnRequest> element are missing. - Section 2.7.3 (<samlp:Response> Usage). Clarification re strongly matching subjects. Additional language in the case where multiple <saml:AuthnStatement> elements are issued (see lines 529--537). - Section 2.7.4 (<samlp:Response> Message Processing Rules). Behavior in the case of multiple <saml:AuthnStatement> elements (basically, SP behavior is unspecified). Removed requirement: "SHOULD NOT rely on any other data."
