Section 5.2 says:

   At least one of the following sub-TLVs MUST be included in the MAC
   Flush Parameters TLV if the C-flag is set to 1:

   o  PBB B-MAC List Sub-TLV:

      Type: 0x0407

      Length: Value length in octets.  At least one B-MAC address MUST
      be present in the list.

      Value: One or a list of 48-bit B-MAC addresses.  These are the
      source B-MAC addresses associated with the B-VPLS instance that
      originated the MAC withdraw message.  It will be used to identify
      the C-MAC(s) mapped to the B-MAC(s) listed in the sub-TLV.

   o  PBB I-SID List Sub-TLV:

      Type: 0x0408

      Length: Value length in octets.  Zero indicates an empty I-SID
      list.  An empty I-SID list means that the flushing applies to all
      the I-SIDs mapped to the B-VPLS indicated by the FEC TLV.

      Value: One or a list of 24-bit I-SIDs that represent the
      I-component FIB(s) where the MAC flushing needs to take place.

It should say:

   At least one of the following sub-TLVs MUST be included in the MAC
   Flush Parameters TLV if the C-flag is set to 1:

   o  PBB B-MAC List Sub-TLV:

      Type: 0x01
      Length: Value length in octets.  At least one B-MAC address MUST
      be present in the list.

      Value: One or a list of 48-bit B-MAC addresses.  These are the
      source B-MAC addresses associated with the B-VPLS instance that
      originated the MAC withdraw message.  It will be used to identify
      the C-MAC(s) mapped to the B-MAC(s) listed in the sub-TLV.

   o  PBB I-SID List Sub-TLV:

      Type: 0x02
      Length: Value length in octets.  Zero indicates an empty I-SID
      list.  An empty I-SID list means that the flushing applies to all
      the I-SIDs mapped to the B-VPLS indicated by the FEC TLV.

      Value: One or a list of 24-bit I-SIDs that represent the
      I-component FIB(s) where the MAC flushing needs to take place.

Notes:

Type definition was error. The PBB B-MAC List Sub-TLV abd I-SID List Sub-TLV are only support for one byte, as defined in section 5.1.1 MAC flush parameters TLV.
This error was imported from draft-ietf-l2vpn-vpls-ldp-mac-opt-12. For this version, it submit the 2 sub-tlv to IANA for alloc id. But the two kinds tlv were sub-tlv, not LDP TLV
