Next steps for XPath profile from WS-Fragment and XML Signature 2.0

All:
Although the WS-RA Working Group has  published a Last Call working  
draft of Web Services Fragment [1] I believe we should still discuss  
producing a common profile of XPath - separating the XPath profiling  
material out of WS-Fragment and XML Signature 2.0 [2] into a new  
separate document.
Bob, the chair of WS-RA, and I briefly discussed this and it appears  
that restructuring material in a document should not affect the Last  
Call status of that material (though I suspect a new XPath profile  
document would probably warrant a new Last Call, in particular for new  
material). However removing the material from WS-Fragment should not  
require a new Last Call of that document.
It seems that now would be a good time to start working on considering  
creating a separate XPath profile document - before WS-Fragment  
progresses further.
To this end I have created a draft document that outlines what the  
differences are and how we can proceed. Corrections and suggestions
