   This document introduces a simple mechanism to associate a group of
   Label Switched Paths (LSPs) via an extension to the Path Computation
   Element (PCE) communication Protocol (PCEP) with the purpose of
   computing diverse (disjointed) paths for those LSPs.  The proposed
   extension allows a Path Computation Client (PCC) to advertise to a
   PCE that a particular LSP belongs to a particular disjoint-group,
   thus the PCE knows that the LSPs in the same group need to be
   disjoint from each other.
