Michael,

I guess that that's possible, but I'd be for getting started
without the dictionary and changing to use it later if it
makes sense than.

But since you've suggested it: what's the easy way to encode
the optional src and/or optional dest optionally using the
dictionary? (I'm just not up to speed on how the dictionary
encoding currently works.)

Stephen.
