Section 7.2 says:

7.2.  VPC Case

   When configured for a VPC cell relay service, both PEs SHOULD act as
   a VP cross-connect in accordance with the OAM procedures defined in
   [I.610].

   The PEs SHOULD be able to process and pass the following OAM cells
   transparently according to [I.610]:

     - F4 AIS (segment and end-to-end)
     - F4 RDI (segment and end-to-end)
     - F4 loopback (segment and end-to-end)

It should say:

7.2.  VPC Case

   When configured for a VPC cell relay service, both PEs SHOULD act as
   a VP cross-connect in accordance with the OAM procedures defined in
   [I.610].

   The PEs SHOULD be able to process and pass the following OAM cells
   transparently according to [I.610]:

     - F4 AIS (segment and end-to-end)
     - F4 RDI (segment and end-to-end)
     - F4 loopback (segment and end-to-end)
     - F4 CC (segment and  end-to-end)

Notes:

As per [I.610] all OAM cells must be transferred transparently , RFC 4717 does not mentioned the F4 CC OAM cell .
