2.1 ActiveSync WBXML Algorithm Details

ActiveSync messages are transported as HTTP POST messages, as specified in [MS-ASHTTP], where the body of the message contains WBXML formatted data. The WBXML data encodes the XML required by the command being communicated in the message. The ActiveSync commands are specified in [MS-ASCMD].

This section specifies the algorithm to encode XML request and response messages into WBXML format and to decode WBXML data into XML request and response messages. This algorithm is used by clients and servers.
