   LOL! Treating my messages like trash... oh well, no big deal.

   I was thinking that there are different cases where mutually 
exclusive sections are used.  For example:
1. In wizard interfaces where the user must sequentially step through
    each, usually with Next and Back buttons.
    This could use something like <sequential> for the container.


   (my preference is for <exclusive>, rather than <mxsection>, simply 
becuase I like actual words, rather than abbreviations where possible, 
and when there's no benefit of either being shorter to type)

2. In options/properties dialogs, or other tabbed interfaces where the
    user can view them in any order, usually with tabs or buttons.
    This could use something like <concurrent> for the container.

   The element names could probably be better, expesially <concurrent>. 
  I wanted an antonym for sequential, and that was the most appropriate 
I could find with my limited research.

   So, effectivly they degrade to unstyled <div> or <span> elements 
(depending on whether it defaults to block or inline styling — I'd 
assume inline, which is effectivly no style at all, but I could be 
wrong)  Either way, I don't see that as a real problem.  User agnets 
with styles disabled or unsupporeted handle <div> and <span> just fine, 
and the content is completey useable (for accessible documents, where 
semantic markup has been used properly).
