Al,
One of the great, continuing philosophical debates within working groups
is whether to bundle all of the parts of the spec together or whether
to break it into pieces.
One of the arguments for breaking into pieces is if one or several of
the parts is likely to be used by other, possibly-unrelated, applications.
In this case, it sounds like you have quite a bit of interest in your
LZJU90 algorithm separate from any debate about email format.
It sounds as if you will be performing a clear service to separate
the spec, therefore.
