Stephen, if you're actually implementing this, you may find Julian's
HTML-Parser package useful.  Also, in the 2.2 release under
Seaside/Alpha-Rendering there's some early support for a parse-tree
building renderer, but I make no promises about anything in the "Alpha"
categories.  Anyway, it would be nice to see some templating ideas start
to come together... I've been studiously avoiding putting any thought into
that side of things, so it's good that you and Colin are picking up the
slack :).

Cheers,
