well, I found the reason. libxml2 does not clone document fragment
nodes, it just returns NULL. I had a quick look at the DOM
specification, it says that cloning a Document is implementation
dependent, but it says nothing about DocumentFragment, so I assume it is
legal to clone it. Maybe Daniel can give us some more details. I would
imagine it is quite easy to clone a DocumentFragment as well, I don't
think it poses any new problems.

I also investigated a bit the DTD loading issue. There is a flag in
Gdome you can use to give attributes their default value from the DTD.
Basically you have to use the mode

	GDOME_LOAD_PARSING | GDOME_LOAD_COMPLETE_ATTRS
	
I don't know if this is enough to load the external DTD. I would ask you
to try. In case it is not enough, we can provide another flag and use
Daniel's suggestion.
