SHARED ONLY TAGS (BOZZA)
------------------------------------------------------------------------------

Shared only [tags] cannot be accessed from the
[User domain]. This can be useful to limit the data
to be transmitted from a JSup [server] to a
[client]; if a shared [tag] with very high change
rate is not needed by the [User domain]. A shared
[Object tag] must be declared Shared only: that's
because there is no standard way to
transmit/receive its value to/from [clients].
