Sure. I personally support a way of providing extensibility so HTML documents
can contain e.g. MathML content without dumping all the MathML elements in the
HTML spec. However, as several people have noted, implementation experience at
Opera suggests using the xmlns attribute for this purpose is not viable for
backward compatibility reasons. To me that suggests using a HTML-only attribute
like subtreeNS might be the way forward; clients that wanted to convert to XML
could replace subtreeNS with xmlns.
