Then what am I to make of Eliot's assertion that XML Linking is 
conforming HyTime.  I admit that I don't have the time to work
out the details of that.  I also don't like restrictions on 
content models.  It is a lot less ugly as deRose has shown 
to use them for linking information.

That is the sticking point.  Is it irrelevant?

I'm not sure if that goal has any utility.  Whereas, 
gratuitous references are not useful, normative references 
establish a chain of authoritative information.  That 
does have utility.  WG8 is very likely to build the 
SGML Lite over XML and that is a win-win for all of us.

Oh, I don't distrust the questions at all.  I wish we had all been 
doing this some years ago online and in this fevered way.  But 
that is past.  What I want to see now is a clear authoritative 
chain of standards expressed as running code and embraced as 
COTS applications.  Then we can all go watch deRose ice skate.
