UCDlist document update

Dear all,

after a first round of comments and suggestions, let me summarize:

1. I think it will be unwise to re-open the discussion on the already standard UCD main document (thus de-classing it back to WD) to ease the approval of a second standard, just because we are too lazy to find a reasonable spelling for a few words!
2. Let?s keep changes to a minimum. I found suggestions on the atmol and flux/sb words very interesting and worth discussing with more time and care. Shortly we will know how to do it ! (http://www.ivoa.net/Documents/latest/UCDmaintenance.html)
3. atmol: I think the simplest solution in this particular case is to change the words phys.at.* into phys.atomic.*
4. ?obtorto collo? (we do it, but we whould have preferred not to do it!) we go for phot.flux.density* and phys.energy.density
5. phys.massToLight can become phys.composition.massLightRatio (indeed the ratio has to do with the barionic composition of galaxies or clusters of galaxies)
6. phys.massYield can become phys.composition.yield (also in this case the new version is better than the old one - mass just indicated units)

I will wait for a few more days before changing the list of words.

Cheers

Andrea
