Hi,

The test langMatches-3 reads:

================================================================
PREFIX : <http://example.org/#>

SELECT *
{ :x ?p ?v . FILTER langMatches(lang(?v), "*") . }
================================================================

With data 

================================================================
@prefix : <http://example.org/#> .

:x :p1 "abc" .
:x :p2 <abc> .
:x :p3 "abc"@en .
:x :p4 "abc"@en-gb .
:x :p5 "abc"@fr .
================================================================

The result-set specifies the answers p1, p3, p4 and p5.  P1 is in conflict
with "11.4.11 langMatches", which explicitely states * does *not* match
literals without a language qualifier.

	Cheers --- Jan
