Hi,

I have done a significant pass over this draft in light of the reviews and
I believe the draft is substantially improved; however, this revision does
not, in my opinion, resolve all of the review comments and another pass
will be needed before a WG Last Call.

Also, one person has suggested changing the target status of this draft
from Proposed Standard to Experimental. I do not have much objection to
such a change. What do others think?

Thanks,
Donald
