I'd like to update the proposal as follows:

WS-ReliableMessaging:
artifactName: TBD
tc: wsrx				
product: wsreliablemessaging
productVersion: 1.1
artifactType: spec
stage: wd
descriptiveName: Web Services Reliable Messaging Protocol Specification
				
WS-RM Policy:
artifactName: TBD
tc: wsrx
product: wsrmpolicy
productVersion: 1.1
artifactType: spec

Note that the product names of these two artifacts differ.
