Dan, many thanks for your comments.
Murray and I are a little busy & distracted right now, but we will try
and respond to these (and the other comments on this I-D) as soon as we can.
It will probably take a couple of weeks, I'm afraid.
* I think that references to HyTime and Dexter are not a bad idea; the paper
has to decide for itself :-) whether it is meant to be a specification or
a discussion document; for the latter, such references are certainly
needed, and for the former I think they are not a bad idea, but it must
be clear if this ever goes onto the standards track that they are in no
way normative, of course!
* On action, style, etc., we have tried in this draft to be inclusive, and
I think if there are any things that are contentions -- as there will be --
that they should be dropped.
* Thanks for the reminder about giving REL and REV multiple values.
