>From what I can gather, XML, XLink, XPointer, and XML Namespaces are all 
projects of the XML Working Group under the XML Activity.  XSL appears to have 
its own Working Group under the Style activity. RDF appears to have its own 
Working Group under the Metadata activity.  XML-Data, WIDL, and a number of 
other proposals are just that - proposals.
Is this an accurate picture?  Is there a roadmap on the W3C site that I simply 
haven't found?
Thanks.
