You (as Paul) didn't read this sentence (quoted here from above):

Any time you see ``MAY'' or ``may'' in the draft and a target
and initiator arrive at different outcomes _just_ by taking one
or the other route, you have ``compliant-non-interoperability''.

Which is what you are describing in more ``baby-terms'' below.

Read my reply to Paul, where I give 2 links to emails
where this is described well -- this has since been fixed
in the draft.

BTW, I don't like ``MAY'' and ``may'' -- I don't use those
two words personally and I sure don't like them in the spec as well.

But you are merely repeating what I'm saying above... (and in my previous
email).
