"Obsolete" doesn't mean old versions of active
specifications, which are superseded by revised versions. Rarely
but occasionally, an OMG specification will fall into disuse or
(as in the case of OpenDoc) no longer be supported by the
company responsible for it (or anyone else). OMG has a procedure to retire such
specifications.
We won't go into detail here. The retirement process involves a series
of votes similar to those required for
adoption, assuring that
all of OMG's members get their say in this important decision.
Only two specifications have been retired so far: The XCMF
management facility, whose functionality in CORBA object
lifecycle management was superseded by the CORBA Component Model
(which, benefiting from years of additional industry experience,
does a much better job) and OpenDoc, which formed part of the
Common Facilities document and information management facilities
before support for it was dropped by Component Integration
Laboratories.
