dB, Hz, octaves, meters, seconds etc.

Preferably from a controlled vocab, but I could be persuaded that free
text strings are a good alternative/addition. Alternativly it could be in
the plugin metadata, but that would make operation depend on metadata,
which is bad practice.

I think they will make port labels less cluttered, and make for better
looking host provided guis.

    <port label="gain" dir="input" type="control">
      <name>Amps gain (dB)</name>
      <range min="-70" max="+70"/>
    </port>

    v's

    <port label="gain" dir="input" type="control" units="dB">
      <name>Amps gain</name>
      <range min="-70" max="+70"/>
    </port>
