 session protocol or when persisting messages in storage.

 #### Field byte alignment
-As an alternative to specifying a field's offset from the start of a block, its byte alignment may be specified. If specified, the start of the a field should reside at an offset from the start of the buffer that is the next multiple of the alignment attribute. If the offset without alignment would not be a multiple of the alignment attribute, then the buffer is padded with octets to that multiple. The padding should be set to binary zeroes.
