SPARUL grammar question for ARQ
According to sparql.org this parses:
DELETE WHERE
{ ?s ?p ?o }
According to the spec empty brackets are required in the construct template.
http://www.w3.org/Submission/SPARQL-Update/#rConstructTemplate
Is this an extension for ARQ, or am I mis-reading the grammar? Is there a
pedantic parser for the updates that would parse only valid 1.1 syntax for
updates (as there is for query) ?

Your reading the wrong spec :-) The ARQ's update parser is pedantic, as
you put it, and that is what you get with syntax SPARQL.
SPARQL Update - as will become a W3C Recommendation is:
http://www.w3.org/TR/sparql11-update/
While the submission was input at the start of the WG process, the
resulting language has moved on.
One feature added is the
DELETE WHERE { ?s ?p ?o }
shortcut
http://www.w3.org/2009/sparql/docs/update-1.1/Overview.xml#deleteWhere
which is equivalent in effect to
DELETE { ?s ?p ?o } WHERE { ?s ?p ?o }

Doh, Google did it to me again. I should have noticed it in the URL.
