Exactly.  I suspect that 100% of the readers of this list agree 100%
with this contention.  In fact, this is already happening - people
are stealing chunks of HTML tags in other XML languages.  Good design, 

But, if I want, in my own XML language, to use an HTML table here and
an HTML hyperlink there, it seems to me the most natural thing in
the world to do this:

<myRootElement xmlns:html="the-namespace-URI-for-HTML">
  <myTag> ...
  <myOtherTag> ...
  <html:a href="adsafa;dfs">sfasafsdj</html:a>
  <yetAnotherTagOfMine> ...

why on earth would I want different namespaces for all these different
HTML modules?  There is no possibility of collisions since they're
all from HTML.  -Tim
