The following section was included in the previous revision of PCELS but it has been removed in the current (-05) revision. For the record, these are the changes in PCELS-04 since PCELS-03:
Changes since -03
1. This revision does not deprecate schema items defined in PCLS.
The "Abstract" of this document has been modified accordingly.
2. To make them easily distinguishable from the object classes and
attributes defined in PCLS, the schema items defined in this document
are now prefixed "pcels" instead of "pcim".
3. In previous versions of this document the pcimPolicyGroup object
class (initially defined by PCLS) was redefined as a subclass of
pcimPolicySet (now pcelsPolicySet). This modification has been
abandoned.
4. Added note on PolicyGroup representation as pcelsRule or
pcelsPolicySet.
5. Abandoned deprecation of pcimRepository and modified
pcelsReusableContainer to subclass pcimRepository.
6. Added general considerations in the opening of the schema
definitions (section 5).
7. Added text to clarify which attributes defined in PCLS are also
used in object classes defined here.
8. Instead of deprecating pcimRuleConditionAssociation and replacing
it with pcelsConditionAssociation, the latter object class has been
modified, so that is now a subclass of pcimRuleConditionAssociation
which is no longer deprecated.
9. Instead of deprecating pcimRuleActionAssociation and replacing it
with pcelsActionAssociation, the latter object class has been
modified, so that is now a subclass of pcimRuleActionAssociation
which is no longer deprecated.
10. The class pcimRule and its subclasses defined by PCLS are no
longer deprecated. A note has been added to clarify the issue
regarding the functionality replacement for compatibility with
PCIM_EXT.
11. The pcimGroupContainmentAuxClass and pcimRuleContainmentAuxClass
object classes defined by PCLS are no longer deprecated. A note has
been added to clarify the issue regarding the functionality
replacement for compatibility with PCIM_EXT.
12. Added text to explicitly describe the use of
pcelsPolicySetAssociation for the realization of the
PolicySetInSystem association. This was unclear in previous
revisions.
13. Revised "Summary of changes since PCLS" in accordance with the
changes listed above.
14. Revised security considerations.
15. Updated normative and informative references.
16. Added section to explain impact on PCLS implementations.
17. Added note on OID assignment status. (before section 1).

19. Added text to indicate valid and default attribute values where
applicable.
