Hi Sacha,

I have looked a bit at libxml2 and it seems that the XML and HTML parser
are really two differents parsers.  And the HTML one unconditionally
does lower case tags ('htmlParseHTMLName' in HTMLparser.c).  My idea was
to see if it was possible to have an option for this but it's not the
case for the HTML parser.

So I think your patch with a correspondence table is the correct one
here.
