Thanks indeed, Karen. This is very useful!

@Rob: my model is an earlier attempt to caracterize what is in ProfileDesc, but it's not so early ;-)
It was at the last F2F. Looking at ProfileDesc, and trying to make sense of it - as you had done already some terminology choices, which I found hard to understand (probably because I missed the flexibility of being able to group notions with slashes ;-) )
