I think that you need to be clearer in your description of 4.  Rather than:
> 4)      an m- line MUST NOT be removed from a BUNDLE group if, in the associated offer, an identical port number was indicated for all m- lines in a BUNDLE group

Use words like unbundled instead perhaps.  And it's not MUST NOT, it's
simply "cannot".
