[gdome]HTML modules

[Paolo Casarini <casarini CS UniBO IT>]

I've already made some changes to gdomecore that involve the HTML
module. What's the future for this module in gdome2 (Anders)? May I modify
it?

I should modify:
- gdome-html.[ch] to change the call createAttrNS to createAttributeNS
in the HTMLDocumentVtab
- gdome-xml-htmldocument.c to update the use of NodeList.

Thanx
Paolo
