Not as far as I know.  It seems a reasonable convention,
but it would be nice to (semi-)standardize it.

Yes.  I don't see it worth tremendous effort, since for real
persentation I use the docbook-xsl stylesheets.  The most
important use I think is it might allow (near-)wysiwyg-editing
of docbook using an xml/html editor.

This is the document I'm currently working on:
http://www.gnu.org/software/kawa/internals.xml (source - now
   directly viewable using stdocbook-css!)
http://www.gnu.org/software/kawa/internals.html (generated
   using docbook-xsl)
[I'm actually working a web-site redesign, but that's not
up yet.]
