   This document specifies how to combine a Backward Recursive or
   Hierarchical method with inter-domain paths in the context of
   stateful Path Computation Element (PCE).  It relies on the PCInitiate
   message to set up independent paths per domain.  Combining these
   different paths together enables to operate them as end-to-end inter-
   domain paths without the need for a signaling session between inter-
   domain border routers.  A new Stitching Label is defined, new Path
   Setup Types, a new Association Type and a new PCEP communication
   Protocol (PCEP) Capability are considered for that purpose.
