blank nodes in predicate position

We're currently testing our new SPARQL parser/engine and ran into an
issue with the DAWG syntax test cases.

According to
http://www.w3.org/2001/sw/DataAccess/tests/data/SyntaxFull/manifest.ttl , specifically DAWG-approved tests syntax-bnodes-03.rq and syntax-bnodes-04.rq, it is legal syntax to have blank node labels in the predicate position. (either [] or _:a).

However, in the current rq24 grammar there is no production rule for
this.  

I vaguely remember this being a topic for discussion but could not find
relevant mail in the archive (btw my firefox 2.0 seems to have some
trouble with navigating the mailinglist archive, anybody else having
problems?). 

So any idea what the current status is? Which is correct, the grammar or
the test case?
