e.g. one trix doc containing all the tests

Yes, see 3) below

Not me.

This would be hard, since Trix-Trix comparison is not yet defined. This is 
one of the things currently being discussed on www-archive as some of us 
try and improve the formal model underneath Trix.

More positively,

jena.rdfcompare [1]

can read two N-triples files and tell you whether they are the same or not.
It implements graph equivalence as defined by RDF Concepts.

I would be surprised if other toolkits do not provide similar functionality.
Hence I would suggest running the test suite thus:

XSLT from RDF/XML => N-triples
use jena.rdfcompare to ompare the answer with the correct result.
