It is per-subsystem.  But nothing in the spec prohibits and implementation
that has multiple subsystems to simply not allocate cntlids that
would conflict betweens it's subsystems.

And in fact there is a TP in the working group that would require
implementations not to reuse cntlids for it to work.  We'll probably
hear more about that once it's published.
