Re: Could you update the GRDDL Service to be compliant with the Spec

I've started running the tests; on testlist1.rdf [4], I get one failure
on the atom test, since it outputs turtle that is not supported by the
XSLT service. 

On testlist2.rdf [5], I get a failure on multipleRepresentations [6],
but this is probably due to the fact that
http://www.w3.org/2001/sw/grddl-wg/td/multipleRepresentations.rdf
doesn't exist. I also fail on the httpHeaders test since I haven't tried
to implement it - I'll try to get a stab at implementing it. 

I failed on multiProfile due to the use of relative URIs in the profile
attribute; I'm not sure this is very kasher - using relative URIs when a
<base href> may get defined later - but the spec doesn't seem to forbid
it, so I made it handle it. testft.py still claims that I fail the test,
but I'm not sure that's true - for some (unidentified yet) reasons, I
get duplicate in the results file (attached), but I'm not sure it really
is against the spec or not.

I fail most tests in testlist3.rdf [7], but since they are "robustness"
tests and this service is mainly experimental, my motivation to fix
those is not very high...

(the EARL outputs of the testing for each of the tests lists is are
attached to this message)

I think it probably makes sense that W3C support a real GRDDL online
service, but I'm not sure the XSLT-based solution is the right base for
this; I agree that starting from a more sound implementation would be
the right thing to do, but I fear I don't have the cycles to set up such
a system anytime soon...
