I look at the opensolaris source code and found this bit of information:)

A zone is a named collection of processes, namespace constraints,and
other system resources which comprise a secure and manageable
application containment facility.

The global zone (zoneid 0) is automatically associated with all

system resources that have not been bound to a user-created zone.
This means that even systems where zones are not in active use
have a global zone, and all processes, mounts, etc. are
 associated with that zone.
