   The stateful Path Computation Element (PCE) communication Protocol
   (PCEP) extensions provide stateful control of Multiprotocol Label
   Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSP)
   via PCEP, for a model where a Path Computation Client (PCC) delegates
   control over one or more locally configured LSPs to a stateful PCE.
   There are use-cases in which a stateful PCE may wish to request and
   obtain control of one or more LSPs from a PCC.  This document
   describes a simple extension to stateful PCEP to achieve such an
