Edward and WG participants.

This question has bee out on the mailing list for quite a while.
Edward already asked for opinions on this back on Dec 7th in a
posting to this mailing list. Since then we've had a couple of
answers that indicate they rather see the current work completed.

So I am inclined to tell the WG that we stick to what we have in
the current draft and do no new additions. I'll give the WG till
the end of this week to speak up more on this topic. If I do not
see more support for Edwards suggested changes, then we'll not
undertake them now.
