In terms of XML, it is the same thing indeed....

If we want to fix the QDom-based reading code to support this,
we'll have to use attributeNS and elementsByTagNameNS (hmm there
is no namedItemNS!), and pass the (rather long) namespace URI
every time.... this isn't going to make things faster.

Personally, I don't think anyone is going to create oasis documents that
way, it would break too many things in non-namespace-aware parsers.
(I wonder if all the XSLT stylesheets around OO are namespace-aware...).
Of course "never say never", etc. .... but I'm just not sure this is worth
the effort until we actually see someone doing this.
