Way cool!

I must say, TAL, METAL and TALES absolutely rock. This is very a very
stellar piece of work, and very consistent throughout. HiperDOM doesn't
even come close. Converting part of the CMF interface worked very well.

Now if only I can get StructuredText to output XHTML. Or have
tal:replace="structure ..." not verify the well-formedness of the XML..
