worker example" or "little house example".
These last two issues will attempt to be discussed in detail in the

10. SPARQL QL grammar
rq23 grammar update Seaborne, Andy (Wednesday, 24 August)
AndyS reported the grammar state - it is now LL(1) and the major
changes are all done. digits and underscores are now allowed at the
start of variable names (VARNAME, rule 84).
Some grammar changes might still happen depending on how any result
of language issues are resolved; could be a new builtin keyword, a
qnamed function, ...
test cases, e.g. SELECT ?x WHERE {.}
ACTION SteveH: review the SyntaxDev grammar tests
ACTION DaveB: review SyntaxDev grammar tests
various comments on variable names, etc.
Looking at SELECT ?x WHERE { <foo###bar> dc:title ?x }
and recent grammar work.
Discussion of wording about how SPARQL references valid IRIs.
Where does it say that a query with an unbound prefix is invalid?
PROPOSED: that SELECT ?x WHERE { <foo###bar> dc:title ?x } is not a SPARQL query string; that Q_IRI_REF's must conform to generic IRI syntax
RESOLVED hayes, harris, andy, ericp abstain.
