Right; a language can and should be specified without reference
to implementations.

And I think it's silly to say that "the word SELECT MUST be
followed by a space"; it's like saying "2 + 2 MUST be 4".
Better to just say "2 + 2 is 4", or in our case, as
you point out below, "A SPARQL query string is a sequence
of characters in the language defined by the following grammar. ...".

No, conformance of strings to the language definition is in scope,
as is conformance of answers to queries. Our last call decision
was a decision that we had specified those to our satisfaction.

The commentor seems to prefer that we organize that material
differently.

Yes, that's the relevant current text.

The commentor is asking for a different organization. That's
an editorial matter. You will please make an editorial judgement
and either
  (a) try to satisfy the commentor with the current text, or
  (b) propose different text in mail to the WG;
   (1) if you think the different text doesn't involve any design
   changes, you can ask that I confirm that, so that you can
   respond to the commentor
   (2) if you come up with design changes while you're at it,
   we'll need to make a WG decision.

The commentor might be satisfied by something like changing the
Grammar section heading to "Grammar and Query String Conformance".
