Example: If you have a CWT authorizing A for audience Z and you now also need authorization B for audience Z, you should request a CWT for A+B for audience Z, that replaces your previous one.

Do I understand?
two possibilities:
A and B are members of audience Z; no new CWT needed
B is a new member of audience Z; then audience Z becomes audience Z-prime and a new CWT seems reasonable.

No Peter,

sorry for being unclear. In my example A and B were permissions. Let me clarify:

You have a CWT authorizing to "read" (that's my A) traffic in group Z, now you also want authorization to "write" messages to group Z (that's my B). What I'm saying is you should get a new CWT that says "read+write on Z" (and not a separate one that says "write on Z" to combine with the first one "read on Z").
