You want DocumentFragment.

But Martin's right (of course): you still need a Document, and you
make fragments by calling Document.createDocumentFragment().

For a headache-inducing example of the use of this (my headache, not
yours, I hope ;-), see

http://wwwsearch.sf.net/DOMForm/


(the parser is in the file DOMForm/_js.py -- it gave me a headache
because everything prior to a chunk of embedded script in HTML has to
be available to the script through the document object, so sometimes
you have to append to a DocumentFragment, sometimes to a node in the
main Document tree)
