I believe the document is essentially ready to go to the IESG. All I
found were a few nits:
1) p4: s/is is/is/
2) p6: s/the the/the/ (occurs twice)
3) p16: I thing the text describing port compression can be somewhat
simplified or less confusing by avoiding the "and elided". Here is
proposed new text:
01: All 16 bits for Source Port are carried in-line. First 8
bits of Destination Port is 0xF0 and the remaining 8
bits of Destination Port are carried in-line.
10: First 8 bits of Source Port are 0xF0 and the
remaining 8 bits of Source Port are carried in-line. All 16
bits for Destination Port are carried in-line.
11: First 12 bits of both Source Port and Destination Port are
0xF0B and the remaining 4 bits for each are carried
in-line.
4) I was asking myself whether more needs to be said in the security
considerations but could not really come up with additional text.
However, operationally, I expect it to be challenging to debug
problems when contexts are used since knowledge about the meaning
of the contexts is crucial to assign meaning to a conversation.
Since the document says how information is maintained in shared
contexts is out of scope, I guess there is not much to be done for
this document, but hopefully some other documents will be written
to make this less of a magic.
