Daniel,

Spring seems to have an interface that says "Hi, I'm a resolvable
Message".  This is similar to the Message object you propose above.

http://www.springframework.org/docs/api/org/springframework/context/MessageSourceResolvable.html

I'm now subclasses ResourceBundleMessageSource to search through the
message args, look for MessageSourceResolvable, and resolve it.

I'm specifically reimplementing the getMessageInternal method from
AbstractMessageSource.  That's a little ugly, but that seems to be the
point where the MessageFormat is used.

Hope that helps,
Seth
