Not necessarily..  It all depends on what the storage requirements are
for Recurrence and how that compares to the storage requirements for
FS.  From where I sit the storage requirements are >95% in parity,
which implies you could just re-use the existing schema and instead of
loading it into a FS you load it into a Recurrence..  And then just
replace /ALL/ uses of FS with Recurrence everywhere in the source
tree.

For the few things that Recurrence does that FS does not, I think
that would work fine -- the new features would be new attributes
and an older FS implementation wouldn't understand them anyways.

I see little reason to make two full xml translation objects when
you can just make a small modification to one parser/generator object.
This just implies a merging of FS into Recurrence...  Which is what
I've been asking for all along.
