Thanks for your support. Based on the feedback received so far the next
version of this draft will recycle Cease subcode 2.

The text is explicit about the length:

    "followed by a freeform UTF-8 encoded string with a REQUIRED maximum
    length of 128 octets. "

and further:

    "This document tries to minimize the effects of visual spoofing by
    allowing UNICODE only where local script is expected and needed, and
    by limiting the length of the Shutdown Communication."

I object to using a TLV. Don't forget this is already at a TLV level:
Cease NOTIFICATION. If one would want to define a TLV inside this TLV, a
new Cease subcode can be requested from IANA.

Kind regards,
