1.4 Relationship to Other Protocols
This protocol describes the XML representation of e-mail message data that is used by the command requests and responses that are described in in [MS-ASCMD]. The protocol that controls the transmission of these commands between client and server is described in [MS-ASHTTP]. The Wireless Application Protocol (WAP) Binary XML (WBXML), as described in [MS-ASWBXML], is used to transmit the XML markup that constitutes the request body and the response body.
For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
