are you planning to create more work for me ? :)
We could certainly dynamically figure out which format to use.
Now the question is are we planning to allow both old and new formats
to be used side by side?
Or do we need to make this a configurable policy?
Perhaps that could be done using a -D option?
Something like -Dqpid.dest.format = {URL,Address,Both}
I am happy with either 'Address' or 'Both' being the default .
What do you think?
