   Current PCEP standards allow only one intended and/or actual path to
   be present in a PCEP message.  Applications that require multipath
   support such as SR Policy require an extension to allow signaling
   multiple intended and/or actual paths within a single PCEP message.
   This document introduces such an extension.  Encoding of multiple
   intended and/or actual paths is done by encoding multiple Explicit
   Route Objects (EROs) and/or multiple Record Route Objects (RROs).  A
   special separator object is defined in this document, to facilitate
   this.  This mechanism is applicable to SR-TE and RSVP-TE and is
   dataplane agnostic.
