What would be ideal is if you could change the syntax table and keymaps in
an extent/text property region.  I know you can do this for keymaps, but I
don't think you can durrently to it for syntax tables.

Then instead of an indirect _buffer_, you would have a region of the buffer
that would in effect be in 'sgml-mode' or 'enriched-mode'.  But you would
still really want the bindings of 'message-mode' to be in effect, so this
points to using minor modes instead of mixing major ones... hmmmm :(

We just need really studly minor mode versions of sgml-mode and
enriched-mode that integrate really well with mail-mode or message-mode.
