I have the read draft-ietf-tsvwg-fecframe-ext-01 during WGLC and have a 
few comments (as an individual),

Gorry

----
The following is stated:
/.   (e.g., because of a congested
    router, of a poor signal-to-noise ratio in a wireless network, or
    because the number of bit errors exceeds the correction capabilities
    of a low-layer error correcting code)./
- while this is true, it is probably wise to assert that most links 
supporting IP employ a CRC or other integrity check to verify this 
correctness, and that this is assumed. RFC3819 may be a suitable reference.
---
The terms RTP and DCCP are mentioned, but the base spec RFCs in each 
case are not cited.
---
/ This section discusses the protocol elements for the FEC Framework./
This section uses requirements language, and therefore the intro para 
needs to say how this applies. - It seems to me that this section does 
more than discuss, and some of it is actually to specify?
