    ** 001 NVS 20050318 NEW   @20446 Created the initial version. This class
    **                               represents associations between an abstract
    **                               resource instance and a list of related
    **                               bindings.
    ** 002 NVS 20060412 CHG   @25492 Made the class and some getters public. Made
    **                               the instance protected from the indirect
    **                               changes.
    ** 003 NVS 20060425 CHG   @25728 Fixed a regression. getBindings() should
    **                               return null if no bindings are set.
    ** 004 NVS 20090415 CHG   @41803 ACL now keeps directory object IDs of the
    **                               objects it was constructed from.
    ** 005 NVS 20090624 CHG   @42842 Simplified due to move to new ACLs.
    ** 006 EVL 20160224              Javadoc fixes to make compatible with Oracle Java 8 for
    **                               Solaris 10.
