Abstract

   This document specifies a number of changes to the Policy Core
   Information Model (PCIM, RFC 3060).  Two types of changes are
   included.  First, several completely new elements are introduced, for
   example, classes for header filtering, that extend PCIM into areas
   that it did not previously cover.  Second, there are cases where
   elements of PCIM (for example, policy rule priorities) are
   deprecated, and replacement elements are defined (in this case,
   priorities tied to associations that refer to policy rules).  Both
   types of changes are done in such a way that, to the extent possible,
   interoperability with implementations of the original PCIM model is
   preserved.  This document updates RFC 3060.
