Supported Transports: This protocol is implemented on top of MSMQ, as specified in section 2.1. It relies on MSMQ message sending and receiving mechanisms to send and receive notifications as messages.
Capability Negotiation: This protocol has explicit capability negotiation that depends on the version of the notification message. There are two notification message versions. Version 1 is for messages sent by an MSMQ Directory Service, and version 2 is for messages sent by a queue manager.<4>
