They are certainly related.  The new issue, though, contains a proposal 
based on
http://lists.w3.org/Archives/Public/public-ws-resource-access/2009Aug/0033.html 
which we agreed to on
http://www.w3.org/2002/ws/ra/9/08/2009-08-18.html.  Perhaps we should 
add this proposal to 6406.
All the best, Ashok
