document-v20 (and subsequently into HTML).


Or if there's a way to add in some extra elements to my document-v20 XML
files (I don't care about validation) and have them transformed, that'd
be fine too.

The document-v20 DTD is to intented to include all the elements in the XHTML2 subset we are working towards supporting. If the elements you want to add are in this subset then you can add them to our DTD, otherwise you should use your own DTD and convert as you suggest.

So, what are the elements you want to add?
