Drat! You are right, of course. And that's a good thing really.

Perhaps it was a bad experience in one particular implementation that
made me think that [...] wouldn't match URI nodes. Or more likely some
other error in my query caused it to fail and I ended up blaming the
square brackets! But certainly ARQ seems to get things right. 

PS: Andy, you may be interested in running 'SELECT * WHERE
{ <http://demiblog.org/vocab/oauth#> rdfs:label ?label }'
at <http://demiblog.org/_sparql> and requesting the result in
text/turtle. It uses your result-set vocab.
