It's not relevant, because it was a how-to question.

That's worrying, as it suggests XHTML 2 has lost focus and RDFa is the
new XML schemas.  This is how standards die.  Soon the only XML application
will be XHTML and that will be the new extensible markup language.

Following is off topic.

If one takes an XML view, I think this should either be left as the 
application specific dialect, rather than converted to the more presentation
oriented, XHTML dialect, and transformed, for rendering, with XSL,
or, assuming that dl is appropriate (which is borderline) it should
be represented as <dd><costello:aircraft_elevation units="metres">12000
</aircraft_elevation></dd>, with appropriate namespace declarations.

This should not be done on browsers that only understand XHTML when served
as text/html.

Exactly, and there wasn't enough to determine that in this case.
