why ? Doesn't HTMLDocument inherit from the standard DOM level 2 Document?

I made the changes in dom/ext/reader/Sgmlop.py and
dom/html/HTMLDocument.py. Those one can easily be reverted, but I think
it'll be much longer to be sure that all XML modules strictly use
NS methods and HTML modules strictly use non NS methods.
Originally, I made the change in Sgmlop to be able to give to Sgmlop a
pDomlette document (which doesn't implement the non NS methods).
Then I have overridden the createElementNS method in HTMLDocument to
delegate in the same manner as createElement, so I don't think it break
the standard HTML DOM behavior if you give to HTMLParser a HTMLDocument.
