I checked that document for the phrase "a port is specified by a port name" but could not find such a phrase.
What the document does say is:
Quote:
Ports and port rights do not have system-wide names that allow arbitrary ports or rights
to be manipulated directly. Ports can be manipulated only via port rights, and port rights
can be manipulated only when they are contained within a port name space. A port right
is specified by a port name which is an index into a port name space.
and this is correct.
Are you sure you understand the concept of namespaces?
