Hi Dave!

A  couple of comments on your message (not on the specs)

BTW Dan, I like the new text on caching - I'm aware of needing to do 
some of that - I have a cache but it doesn't comply with your new text 
(which is appropriate, it was done in too much of a hurry)

My implementation must read this doc, because I don't have a hard coded 
rule for profileTransformation, but rely on the GRDDL transform of the 
GRDDL profile.

Not clear from your message, but my understanding is that it is *not* 
required for GRDDL profile to be explicit in that list. If any of the 
profile docs has a GRDDL transform, with a profileTransformation triple 
in it, then that applies.

The test for this has an explicit mimetype "text/rdf+n3" declared within 
the XSLT. The Jena impl uses that to select the parser. No sniffing.

Other, I have some more tests at:

http://jena.sourceforge.net/test/grddl/

Most assume XSLT 2.0; some are Saxon specific. Quite a few deal with 
security issues.
