In draft-ietf-pwe3-control-protocol-08.txt, the PW Grouping TLV is described
as:

   The PW Grouping ID is an arbitrary 32 bit value which represents an
   arbitrary group of PWs.  It is used create groups PWs; for example, a
   PW Grouping ID can be used as a port index, and assigned to all PWs
   that lead to that port.  Use of the PW Grouping ID enables one to
   send "wild card" label withdrawals, or "wild card" status
   notification messages to remote PEs upon physical port failure.

Surely the figure is not correct since the text speaks of a 32-bit value and
not a parameter ID and a variable length value. The figure looks a lot like
the one above in draft-ietf-pwe3-control-protocol-08.txt for Interface TLV,
