Field Descriptions

WS-RM defines a one way sequence. The sender (source) is called the RMS (reliable messaging source) and the receiver (destination) is called the RMD (reliable messaging destination). Therefore for in-out operations, the RM uses two sequences. For request messages the server acts as the RMD and for response messages, the server act as the RMS.
