[Fwd: minor technical: A.7 grammar, rule [25] Constraint] punctuationSyntax from Dan Connolly on 2006-01-13 (public-rdf-dawg@w3.org from January to March 2006)

On some other syntax-related comments, I just cited our punctuationSyntax records and asked if that makes him happy. In this case, I don't feel I can defend our decision. Anybody else care to draft a reply? Souri, perhaps? 1/2 ;-) -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E

Appendix A.7 grammar
Rule [25] "Constraint" permits a FILTER to be followed by a BuiltInCall
or FunctionCall.  While this is parsable and might occasionally be
used in queries (see examples in section 11.2.3 "Operators introduced
in SPARQL"), it would be better from a
consistency standpoint to eliminate this possibility, as BuiltInCall
and FunctionCall are varieties of Expression. In that case the rule is
simply that FILTER is always followed by a parenthesized expression.
