I don't think this is an editorial matter...

The WG made a relevant decision, no?

Yes... on issue 5.8 datatypes, Dec 12
http://www.w3.org/2001/sw/WebOnt/webont-issues.html#I5.8-Datatypes
http://lists.w3.org/Archives/Public/www-webont-wg/2002Dec/0205.html

So there's a question of whether Jeff Pan's comment constitutes
sufficient new information to re-open the decision.

I don't feel confident speaking for the chairs on this matter,
so I can't authorize you to send this on behalf of the WG,
Peter.

Jim/Guus, please consider this; some options I see:

 --  let us know before sending out this week's agenda that
  you don't see sufficient information to open it, or 

 -- re-open the issue and put it on this week's agenda

 -- put it on this week's agenda to solicit advice about
  reopening it, or to discuss the response, or whatever.


oops; did I ever do this?
"NEW ACTION Dan - to communicate with XML schema group about URIs for
XML datatypes."?

Hmm...
