Hi Ben,

Thanks for your review!

As the MUX category issue is discussed in a dedicated thread, I will not address it in this reply.
 
>    §4: "The fmt (format) list is not applicable to BFCP. The fmt list of ’m’

I will modify to "any other value MUST be ignored".

I don't think referencing section 7 would help, because it only talks about the TCP roles.

I suggest to remove the "Typically,.." sentence.

Well, it IS said in the second sentence, but I will add the suggested text.

---
    
>    §10, 3rd paragraph: Incorrect comma use in "... SDP), in ..."

I will remove the comma.

---

>    §10.1, last paragraph: "... value, in the offer, ...": The first comma is
    incorrect.

I will remove the comma.

---

> §10.3: First paragraph: "When the offerer receives an answer, which
>    contains an ’m’ line..." s/ ", which" / "that"
  
I will change to "that".

---

I will make the reference normative.

Regards,

Christer
