thanks a lot for the review, I'll try to address all your comments soon.
So far only on the general comments, please see below. 8-)

We intend to have the mapping from the component model to RDF, not
directly from the XML. But at least I am planning to create an XSLT
transformation as one implementation of this, so if it looks correct and
complete, it might also become a part of the spec itself.

I believe you are talking about the status section - it is intentionally
direct and threatening so that people actually speak up if they would be
the customer base. If the only identified value would be the exercise
itself, putting the result as a Note would be enough, but the charter
currently says it should become a Rec.

I will try to provide such a list. However, I don't think now that it
would be useful to provide a full list; instead I will aim for a list of
examples and major things.

Thanks a lot again, I'll reply to the rest later,
