Section 4 says:
The Reply Path TLV contains one or more nested sub-TLVs that can be used
It should say:
The Reply Path TLV contains zero or more nested sub-TLVs that can be used
Notes:
As section 4.2 correctly states, the Reply Path TLV can contain zero
sub-TLVs; this brings section 4 inline.

Section 5.4 says:
When an echo reply is received, if the Reply Mode is "Reply via Specified Path" and the Reply Path return code is "The echo reply was sent successfully using the specified Reply Path", and if the return path is an MPLS LSP. The ingress LSR MUST perform FEC validation (based on the FEC Stack information of the return path carried in the Reply Path TLV) as an egress LSR does when receiving an echo request, the FEC validation process (relevant to "ping" mode) defined in Section 4.4.1 of [RFC4379] applies here. When an echo reply is received with return code set to "Malformed echo request received" and the Subcode set to zero. It is possible that the egress LSR may not know the "Reply via Specified Path" Reply Mode, the operator may choose to re-perform another LSP ping by using one of the four Reply Modes defined [RFC4379].

Notes:
In the first two paragraphs of section 5.4, the conditional clauses and the main clause have been separated by periods, not commas, which creates uncertainty as to whether or not text of the main clause has been elided. This changes the periods into commas.

Section 4.3.1 says:
the recommended type value is 26.
It should say:
the type value is 26.
Notes:
The WG commended a value of 26 to IANA for the "IPv4 RSVP Tunnel sub-TLV
Type" which IANA confirmed. Leaving in the 'recommended' introduces a
element of uncertainty that is best avoided.
