COMMENT:
----------------------------------------------------------------------


Thanks for the work everyone put into defining this mechanism. I have one
very minor comment that the authors may wish to take into account.

ยง3.3:

>     /alg/ 3 : /HMAC256//256/ 5,

This use of "//" seems problematic, given RFC 8610's vague reservation of this
sequence for some kind of "comment to end of line" designation:

   (There are currently no end-of-line comments.  If we want to add
   them, "//" sounds like a reasonable delimiter given that we already
   use slashes for comments, but we could also go, for example,
   for "#".)

Given the potential ambiguity introduced by RFC 8610, perhaps
consider some other syntax here instead of "//".
