        Title           : Update to Include Route Object (IRO) specification in Path Computation Element communication Protocol (PCEP)

   The Path Computation Element Communication Protocol (PCEP) provides
   for communications between a Path Computation Client (PCC) and a PCE,
   or between two PCEs.  RFC 5440 defines the Include Route Object (IRO)
   to specify network elements to be traversed in the computed path.
   The specification did not specify if the IRO contains an ordered or
   un-ordered list of sub-objects.  During recent discussions, it was
   determined that there was a need to define a standard representation
   to ensure interoperability.

   An informal survey was conducted to determine the state of current
   and planned implementations with respect to IRO ordering and the
   handling of an attribute of the IRO's sub-object, the Loose hop bit
   (L bit).

   This document updates RFC 5440 regarding the IRO specification, based
   on the survey conclusion and recommendation.
