The "automatic" part of my proposal was really intended to address the
HTML distributed extensibility in an environment in which too many
people had developed an xml-colon allergy. So I wrote it in such a way
that no colons were needed anywhere. However, it'd be pretty easy to
process the namespace definition file with XSLT and produce XML
documents marked up with prefixes.

I'm providing a mechanism by which unprefixed attributes in the XML
input would be recognised as belonging to a different namespace and
moved automatically, rather like an HTML Web user agent moving a "math"
element into the MathML namespace (although I think in the end they
decided to take the Borgian approach and incorporate everything into
HTML, but that was still in question when I was first working on this).

You would in general get a different data model parsing an XML document
with an Unobtrusive Namespace Processor and a regular XML processor.
