1.4 Relationship to Other Protocols

This specification is a profile of the protocols listed in section 1.3. In addition, it relies on a number of underlying protocols. The exchanged messages are based on SOAP [SOAP1.1] [SOAP1.2-1/2007] over XML [XML]. It further requires a transport. This document does not specify the transport to use but relies on the transport to provide message integrity and protection since it does not specify support for it itself.
