    That is hinted at in my previous comments.

    Why do we need semantic mutual exclusion at all? It seems to be some 
kind of semantic justification of the presentational value of having a 
group of sections where only one can display at a time. On a practical 
level, just how useful is non-presentational mutual exclusion in markup?

    Quick note: I have to say, I don't like the header tags being 
treated as tag labels. There are cases where we've done something 
similar, but only when absolutely necessary. I'm a little concerned that 
we're getting too clever with our markup rather than having a 
straight-forward standard.

    My <tabstrip> is actually more powerful, because it allows tabs to 
be used separately from the sections concept. For instance, the 
<tabstrip> could be used with frames:

     <tab for="section1.htm" target="main">Section 1</tab>
     <tab for="section2.htm" target="main">Section 2</tab>
     <tab for="section3.htm" target="main">Section 3</tab>

    It could also be used with simple Javascript events, so vendors 
could keep tabstrip even if they decide to pass on <section>.

    What is the motivation for passing on the <deck> of <cards> 
metaphor? To presentational in nature?
