Re: Draft SystemC LRM for review - URGENT!

Yes, without the corner cases it would be perfectly fine to add it. But
not necessarily required, is it? IMHO, the rest of the rules already
imply that the process is not made runnable just by calling enable.

  The implementation-defined behaviour is not allowed to break this
normative rule. Maybe we can move it to a NOTE or make it otherwise
non-binding (the "shall" is the problem, I think?).

Thanks,
  Philipp
