I'm actually working on this now. I noticed we had a slight inconsistency in the spec, as to whether the document was still valid (in the expiration sense) at the exact time instant specified by <Expires>. In clarifying that, I've also changed the wording: The <Expires> element contains a dateTime value which indicates the time instant at which the document has expired. I agree that the term "valid" can be somewhat ambiguous, especially when used in a specification defining an XML language. Does that answer your questions, or is there still more there that could use additional clarification? > 2.

We discussed that on this call this last week, and I will be moving that up into the Rel section today. -will
