Many thanks for your comments.
Item 16 is now dated.
In Item 17, we refer to IEEE 1588. There are no other projects of similar
scope.
Item 20b is now answered.
In the PAR Scope we have clarified that this mechanism relates to networks
"...composed of LAN media where the transmission delays are fixed and
symmetrical; for example, IEEE 802.3 full duplex links", and have removed
the conflicting wording from the 5C, where it was superfluous.
There are a small number of other minor typographical changes.
The revised draft PAR and 5C can be found here:
