SPARQL test results for RDF::Query 2.0

Hello,

I've just released RDF::Query 2.0[1], and have attached a new set of  
SPARQL tests results.

These tests are still failing:

http://www.w3.org/2001/sw/DataAccess/tests/data-r2/optional-filter/manifest#dawg-optional-filter-005-not-simplified
http://www.w3.org/2001/sw/DataAccess/tests/data-r2/open-world/manifest#date-2
http://www.w3.org/2001/sw/DataAccess/tests/data-r2/open-world/manifest#open-eq-12
http://www.w3.org/2001/sw/DataAccess/tests/data-r2/open-world/manifest#open-eq-07

My understanding is that these four tests are all optional (the open- 
world tests because of values for mf:requires, and the optional-filter  
test because it conflicts with #dawg-optional-filter-005-simplified).  
Is this correct?

thanks,
gregory williams
