More on that separately, in reply to your "external storage" comment.

OK, we're adding a reference to charmod; in the editor's draft,
you may find:

 A. SPARQL Grammar

A SPARQL query string is a character string (c.f. section 6.1 String
concepts of [CHARMOD]) in the language defined by the following grammar,
starting with the Query production. 

 v 1.441  2005/07/26 09:01:47

As to implementations, the QL spec just specifies the semantics of
the language; it doesn't specify any software components. The last
call draft had a few references to implementations, but those
have been removed from the editors draft (in v 1.442) in response
to a few of the comments you made.

The protocol spec (still in progress) specifies a network protocol
between components. For example...

"Thus, the query operation contained in the SparqlQuery interface may
return, in place of the Out Message, either the MalformedQuery message
or the QueryRequestRefused message"
