> The AMQP spec allows 2 eqiuvalent encodings for message-annotations, delivery-annotations, application-properties and filter-sets if there are no annotations/properties or filters. They can either be encoded as missing property values in the message/source or as empty map values.
> Proton should always encode as a missing value. This is the more compact representation, and  more inter-operable since some incorrect AMQP implementations are confused by a present but empty map.
