> When sending AMQP type null as the content of a message, the Python binding sends the message with no body at all, and similarly interprets a no-body AMQP type message as a null type. This violates the AMQP 1.0 specification on two counts:
> * A body MUST be present and be one of three types (section 3.2);
> * When sending an AMQP null type, there is an assigned AMQP type code (0x40) which should be used.
> This causes interoperability issues with other clients. For example,  the C++ client can't send a null type to a python client without a failure (or _visa versa_).
