I have no problems with the publication of this document.  I do have one, non-blocking, question...

Section 3.1 describes the APSI and provides the following statement : "If no identifier is provided, the length field
   MUST be set to zero."

Is there a scenario where the APSI SDES item would be included without an ID being provided?

3.1 "This item MUST be ignored by applications that are not configured to make use of it." That's a very odd construction. It sounds like you're saying that if I'm configured to ignore it, I MUST ignore it. What are the circumstances you are trying to prevent here? I don't understand.

4.2 "The length of this report block in 32-bit words minus one." Perhaps this is an RTCP thing, but this seems like it's destined for confusion. First, instead of using length in bytes, you're using length in words. Do you really think that it is likely for a future block to be longer than 16K 32-bit words? Also, calling it the "block length" but then not having it be the length of the block seems like it's going to cause confusion. If you're going to stick with count of 32-bit words, call it "extension word count" or something like that.

The short-title that shows in the header of each page beyond the first could be more descriptive. Perhaps "Measurement Identity and Duration"?
