Folks,

This has no status whatever, of course, but I decided to checkin the
latest RNC schema for SparqlX into CVS, in case others wanted to look
at or work on it.

It's valid and improved over the last version I sent to the list. In
particular, there was a spurious <pattern-group> element that's been
removed completely. As well as a few other changes, mostly to
cardinalities of some stuff arising from Andy's comments.

Once someone on Team makes it accessible, it should be available as

     http://www.w3.org/2001/sw/DataAccess/sparqlx.rnc

And I'm including it in this message, as well.
