    Would someone please explain the compatibility issues between the various
    releases of X (10.4 --> 11.4).

Version 10 and Version 11 of X are completely disjoint.  Version 10 is
obsolete.  Compatibility with MIT Release N of Version 11 is explained
as part of Release N+1, in the release notes and other documentation.
In general, we try to be upward compatible.  This is especially true for
interfaces which are Consortium standards.
