I'd see two points: overriding and precedence order. I.e. the DITA folks
want to be able to use @dita:translate in exact the same way as
@its:translate.

Of course <mapMarkup> does not solve all problems, but only the ones of
DITA. For the other ones, we need the "normal" global rules, and have to
say: for cases like trans='false' you are not able to use that markup in
the same way as ITS local markup.

Again the question is just if we need this functionality. If not, I'd be
fine to give up my proposal :)

Btw., XBL, to which Richard pointed me a while ago, does the same thing
as mapMarkup for SVG: elements from other namespaces can be used with
SVG semantics. That is: *only* elements, not XPath, to be able to
provide 100% reliable "mapping", see
http://www.w3.org/TR/2005/WD-sXBL-20050815/
