              MessageUnsafe

The lightweight class for catalog entries, for read-only applications.

Unlike the Message, this class does nothing special with attributes. The interface attributes are implemented as in Message_base, where the starred lists are standard lists, starred sets standard sets, etc. There is no assignment and type checking, nor modification monitoring. You should use this class when messages are not expected to be modified, for the performance benefit.

The top modification counter still exists, but only as an ordinary inactive attribute, which the client code can manually increase to signal that the message has changed. This may be necessary for some client code, which relies on top counter to function properly.
