I think we're calling those "bus types" - they are the two different
standard daemon instances with defined ways to locate them.
Bus names are the names managed by the bus that refer to apps connected
to the bus.

--system/--session chooses the systemwide daemon, vs. the daemon running
in the user's session. --dest is which app on the bus to send a message
The glossary in the spec and/or the diagram on the home page may or may
not be helpful, not sure.
