1.4 Relationship to Other Protocols
A client that implements this protocol can use the Autodiscover Publishing and Lookup SOAP-Based Web Service Protocol [MS-OXWSADISC] or the Autodiscover Publishing and Lookup Protocol [MS-OXDSCLI] to identify the target endpoint (4) to use for each operation.
This protocol uses the SOAP protocol as described in [SOAP1.1] to specify the structure information exchanged between the client and server. This protocol uses the XML protocol as described in [XMLSCHEMA1] and [XMLSCHEMA2] to describe the message content sent to and from the server.
For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
