Re: [Quickfix-developers] Order Type value (Market on close)

[Oren M. <ore...@ya...>]

The deprecation process is a little kooky and somewhat
manual.  When whole fields are deprecated it is pretty
easy because we just move the whole field to a
deprecated file and old versions continue to use it
happily.  What we currently don't handle so well is
the deprecation of some enumeration values within an
otherwise currently useful field.

The problem lies in the fact the the fields are
generated off of the most current XML, in this case
4.4.  These situations are so far pretty rare,
although they have become more common with the release
of 4.4.  What we may have to do is update the field
generator to use all available data dictionaries for
all supported versions, which will contain a union of
supported enumerations.

Other options are to create versions of each field in
different versioned namespaces like we do with
messages, but would personally like to avoid that kind
of bloat if possible.  Another possibility would be to
have separate enumeration groups for each version so
we would do things like OrdType_42_MARKET_ON_CLOSE.

I'd definately like to hear suggestions on this as it
will probably become a more serious issue with the
next FIX release.
