I have made a series of updates to the SPARQL language document:

     http://www.w3.org/2001/sw/DataAccess/rq23/

Most notable:


A/ Section 6: More Pattern Matching – Alternatives

Text added that uses UNION to handle alternatives, having looked through the 
email traffic on the comments list, on this list and on what various systems do 
about it.  I had a brief conversation with Steve before travelled to let him 
know I would be doing this.


B/ Section 3 : renamed to "Working with RDF Literals"
3.1 Matching RDF Literals
3.2 Constraining Values (the previous section 3).

Section 3.1 will enable text to be moved out of section 12: section 12 can then 
be descriptive of the F&O operators/functions we will have.


C/ Results from SELECT are sets (but implementations may include duplicates
   unless DISTINCT).


D/ triple pattern grouping is now {braces} (except for [] optionals)


E/ ASK examples done: one that asnwers "yes" and one that answers "no"
