RE: OMA Specification that may be highly relevant to EDXL work. Check it out.

I dug around the Open Mobile Alliance (OMA) site - actually looking 
for standards info OASIS can use as part of their EDXL work. Reviewed a document 
titled OMA-TS-Presence_SIMPLE-V1_0-20050427-C. The 
intro paragraph states:

The document defines an application level specification for the 
OMA SIP/SIMPLE-based Presence Service. It defines the presence information 
semantics for presence information conveyed using the Presence Information Data 
Format (PIDF) the Rich Presence Information Data Format (RPID) and geographical 
information conveyed in a GEOPRIV location object (see [PIDFLO]) specified by 
the IETF in conjunction with the overall Presence Data Model defined in 
[PRESDATAMODEL].

In the bowels of this document is a summary diagram:

There are many sections on notification, rules, etc. 
Within the EDXL vocabulary, the Presence source would be any entity providing an 
event notification. A watcher is any entity who has subscribed to receive 
notifications based on a set of rules. The rules also constrains the actual 
content provided to the watcher.
