Backward Compatibility

The Backward Compatibility plugin adds several internal measures intended to enhance backward compatibility for user interfaces originally created for 1.x versions of CWIS.  (These measures were originally included as part of the core software in CWIS 2.x, but were moved into a separate plugin to reduce overhead for sites where they are not needed.)

This is only useful if you have a CWIS 1.x customized user interface you're trying to use with CWIS 2.x or later;  it is not needed if your customized interface is based on a newer version of CWIS.
