In Ant's distro (I think, else in SVN HEAD) you can
check out the cooperation between fetch.xml and
get-m2.xml . This does something like what you're
talking about.

Um, when you taskdef a resource whose basename is
antlib.xml, you're using antlibs. The advantage IMO
of using the xml ns mapping I pointed to is automation
and terseness. The fetch.xml example shows that it
can be used at an arbitrary level e.g.
project/target/sequential as well.
