Yes, that's what I meant.

Can you explain what you mean by 'multiple transforms' -- alternative
ones or sequential ones? What's the use case for them in TriX?

Of course if you have a TriX mechanism for specifying TriX transforms,
that doesn't prevent you in any way from also including an
<?xml-stylesheet?> for a transform to HTML or XSL-FO or whatever. Having
alternative transforms of an XML file into the TriX plain triples format
doesn't seem very useful, a single deterministic mapping seems the only
reasonable thing to do there :-)

Ok, I didn't know about profiles, was just reading the section that
talks about media descriptors (it didn't link to profiles).

Gn, then that doesn't help :)
