But it is not solving the problems:
1. The PortName still needs to describe the possible values for non
RDF-capable hosts.
2. The host still needs to know what part of the PortName it may
suppress.
My proposal loses us nothing: because plugin authors need to use the
PortName field to describe port values _anyway_ (to aid non
RDF-capable hosts) it makes sense to agree on a best way to do it.
