Yet another RDFa experience

Dear RDFa folks,

I'm taking more tests and implementations of RDFa. This is my
experience on RDFa serialization. I try to make RSS version of RDFa.
So after a mail with Fabien for it's XSLT and transformation, I'm send
to all  this case. To be clear this is the Scenario:

Ingredients:

[1] - RSS in RDFa
[2] - Inspiration RDF
[3] - RDF/XML extraction via XSL (using lastes RDFa XSL by Fabien)
[4] - RDF/XML extraction via Distiller (rdfa.php is a temporary proxy
to Ivan's RDFa Distiller)
[5] - Triples of [2]
[6] - Triples of [3]
[7] - Triples of [4]
[8] - RSS validation of [3]
[9] - RSS validation of [4]

Cooking:

The question is: if the triples are similar, the RDF serialization changes
more and the RSS [3] doesn't validate [8] (not found rss:channel) and
RSS [4] yes [9]. RSS validator expects rss:channel with fixed
serialization but, as Fabien said, this is not possible with a generic
stylesheet for extraction of RDFa. So, more feed readers accpets and
reads [4] but not [3].

In a true philosophical  RDFa and GRDDL way, what is better? A
dedicated stylesheet? Another transformation after Fabien's XSLT? A
third way?

Cheers,

Simone
