I consider the two parts of styling to be quite different, and I would
have liked to get two different names. But I do not have a proposal for
them yet. So we might keep with style for now. It seems to be the most
appropriate term in the end...

There are significant differences between the two, and I don't think we
can get something clean and non-confusing by merging the two. I suggest
going with Ryan's proposal. When we're done, we might investigate ways
of expressing RDFish styling rules based on this (by investigate I mean
see if we could propose something appropriate, not necessarily do it).

Agreed.

The same as yours.

2nd option. I have started working with somebody in the
biology/comp.sci. on an extension of FSL for their own RDF modelling
purpose, and it would really be great to have a "published" version (at
a astable URL) of our work. Other people I'm starting working with here
at INRIA might also be interested in the whole Fresnel solution very
soon. So I'd like us to keep going and produce something good before summer.
