Thanks Joe.  We consider all these different attributes of the object 
(agent, person or object)... some are more dynamic than others, some are 
always static and can never change.  This is a continuum.  It would be good 
if dynamic attribute/status changing was a general concept in Jabber 
exchanges... presence and location then being specially defined aspects of 
these with agreed syntax.

This very general abstract model allows for quite intelligent processing of 
these incoming changes as alterations in "state" or constraints" related to 
the objects, agents or people.  This has quite profound (very positive) 
implications for the ease of use of semantic web services that can involve 
intelligent collaboration between agents and services over Jabber.
