* @ref: publishing port reference

*
* ===> All fields are stored in network byte order. <===
*
* First 3 fields identify (name or) name sequence being published.
* Reference field uniquely identifies port that published name sequence.
* Key field uniquely identifies publication, in the event a port has
* multiple publications of the same name sequence.
*
* Note: There is no field that identifies the publishing node because it is
* the same for all items contained within a publication message.
