That's essentially the effect I want to achieve. As
for global blah, I am more interested in doing things
on a POJO basis; I think there are plenty of solutions
out there anymore that would allow a user to automate
the config for multiple instances that there's no
percentage in resorting to weird tricks to get all
instances of the proposed ExtendedMessageFormat to use
the same custom delegate formats.
