Type: Technical
Reported by: Matthew Bocci <[email-masked]>

Section: 10

Original Text
-------------
In order to support this
requirement, IANA has changed the code point allocation scheme for
the PW Associated Channel Type be changed as follows:

   0 - 32751 : IETF Review
   32760 - 32767 : Experimental

Corrected Text
--------------
In order to support this
requirement, IANA has changed the code point allocation scheme for
the PW Associated Channel Type be changed as follows:

   0 - 32759 : IETF Review
   32760 - 32767 : Experimental
   32768 - 65535 : IETF Review

Notes
-----
There are some gaps in the specified allocation policy for some parts of the ACH channel type range (32752 to 32759 and 32768 to 65535). The channel type is a 16-bit value, and the IANA considerations section of RFC5586 should be updated to reflect this.

I propose that the correction should be to clarify that the allocation policy for the code points that have been left out of RFC5586 is IETF review (which I believe reflects the WG consensus at the time of publication), and to leave the Experimental range where it is to avoid impacting current implementations.

This also requires an update by IANA to the PW ACH Channel Type registry.
