Section 5.2 says:

-  Group ID

   An arbitrary 32-bit value that represents a group of PWs that is
   used to create groups in the PW space.  The group ID is intended
   to be used as a port index, or a virtual tunnel index.  To
   simplify configuration, a particular PW ID at ingress could be
   part of the virtual tunnel for transport to the egress router.

It should say:

Abstract says:

   It is also possible to use pseudowires to
   provide low-rate Time Division Multiplexed and a Synchronous Optical
   NETworking circuit emulation over an MPLS-enabled network.  This
   document specifies a protocol for establishing and maintaining the
   pseudowires, using extensions to Label Distribution Protocol (LDP).
   Procedures for encapsulating Layer 2 PDUs are specified in a set of
   companion documents.

Section 5.3.2 says:

(2nd-to-last paragraph on page 13)

   The PW information length field contains the length of the SAII,
   TAII, and AGI, combined in octets.  If this value is 0, then it
|  references all PWs using the specified grouping ID.  In this case,
   there are no other FEC element fields (AGI, SAII, etc.) present, nor
   any interface parameters TLVs.

Section 5.1 says:

(page 8, the first 2 tables)

   This document specifies the following new TLVs to be used with LDP:

   TLV                    Specified in Section     Defined for Message
   ===================================================================
   PW Status TLV                  5.4.2            Notification
   PW Interface Parameters TLV    5.3.2.1          FEC
   PW Grouping  ID TLV            5.3.2.2          FEC


   Additionally, the following new FEC element types are defined:

   FEC Element Type        Specified in Section    Defined for Message
   ===================================================================
   0x80                            5.2             FEC
   0x81                            5.3             FEC

It should say:

   This document specifies the following new TLVs to be used with LDP:

   TLV                      Specified in Section   Defined for Message
   ===================================================================
   PW Status TLV                    5.4.2          Notification
|  PW Interface Parameters TLV      5.3.2.1        with FEC TLV
|  PW Grouping ID TLV               5.3.2.2        with FEC TLV


   Additionally, the following new FEC element types are defined:

|  FEC Element Type     FEC Element Name          Specified in Section
   ===================================================================
|  0x80                 PWid                               5.2
|  0x81                 Generalized PWid                   5.3

Notes:

wrong term(s) used in table(s).
Apparently, "FEC" is not appropriate in the last column of the first
table, and "Defined for Message" makes no sense in the second table,
where only "FEC" appears, as "FEC" is not an LDP message, it is a TLV.
Perhaps, the latter column is dispensable, in favor of a new column
showing the name of the FEC element.

-- VERIFIER NOTES --
The editors should look at this if there is an update.

The table is a quick index to information about a specific FEC and likely will be removed in a future version of this RFC.

Notes:

message diagram incomplete.

Rationale:
a) using defined terms verbatim
b) final TLV added: PW Grouping ID TLV

-- VERIFIER NOTES --
The editors should consider this in an future revision, but as the PW Grouping ID TLV is optional it could be addressed in the diagram or with a note.

Section 6.3 says:

a) The first paragraph of Section 6.3, on page 22, says:

   As mentioned above, the Group ID field of the PWid FEC element, or
   the PW Grouping ID TLV used with the Generalized ID FEC element, can
   be used to withdraw all PW labels associated with a particular PW
   group.  [...]

   As mentioned above, the Group ID field of the PWid FEC element, or
|  the PW Grouping ID TLV used with the Generalized PWid FEC element,
   can be used to withdraw all PW labels associated with a particular PW
   group.  [...]

b) The second paragraph of Section 6.3, on top of page 23, says:

   If the Generalized FEC element is used, the AGI, SAII, and TAII are
   not present, the PW information length field is set to 0, the PW
   Grouping ID TLV is included, the Interface Parameters TLV is not
   present, and the Label TLV is not present.  For the purpose of this
   document, this is called the "wild card withdraw procedure", and all
   PEs implementing this design are REQUIRED to accept such withdrawn
   message but are not required to send it.  Note that the PW Grouping
   ID TLV only applies to PWs using the Generalized ID FEC element,
   while the Group ID only applies to PWid FEC element.

It should say:

|  If the Generalized PWid FEC element is used, the AGI, SAII, and TAII
   are not present, the PW information length field is set to 0, the PW
   Grouping ID TLV is included, the Interface Parameters TLV is not

--VERIFIER NOTES--
The terminology in the RFC is correct.
It is the "generalized PW FEC Element" and not the "generalized PWid FEC element"

Section 5.4.2 says:

   The PW FEC TLV SHOULD not include the interface parameter sub-TLVs,
   as they are ignored in the context of this message.  When a PE's
   attachment circuit encounters an error, use of the PW Notification
   Message allows the PE to send a single "wild card" status message,
   using a PW FEC TLV with only the group ID set, to denote this change
   in status for all affected PW connections.  This status message
   contains either the PW FEC TLV with only the group ID set, or else it
   contains the Generalized FEC TLV with only the PW Grouping ID TLV.

   As mentioned above, the Group ID field of the PWid FEC element, or
   the PW Grouping ID TLV used with the Generalized ID FEC element, can
   be used to send a status notification for all arbitrary sets of PWs.
