Hi Rob,

The WG will look at your entire message, but I just wanted to address 
this point. In the wake of recent substantial changes to the query 
specification (e.g. property paths counting semantics and the VALUES 
clause, as you mention), the WG will be publishing another Last Call 
Working Draft of the SPARQL 1.1 Query specification, as per W3C process. 
This will give several weeks for the WG to consider and address comments 
and questions from the user and implementer communities.

Before proceeding beyond Last Call (whether to Candidate Recommendation 
status or to Proposed Recommendation status, which the group is indeed 
considering), the group will approve and publish a complete test suite 
that reflects the final details of the query language. Before proceeding 
to Proposed Recommendation stage, the group will produce an up-to-date 
implementation report based on the final test suite.
