yes, i wondered myself. you can simply drop the version 2 condition
(the use of the hint bit implies version 2 anyway). though it will
be nice to connotate features with version dependency so coders
will know when they leave backwards-compatible terrain.

>2. Given a port number, how does the host find the PortValEnum ?

it's in the test program posted with the first patch:

  /* (d = LADSPA_Descriptor * for the plugin) */
  for (i = 0; i < d->PortCount; ++i)
  {
    printf ("--------------------------------------------\n");
    printf ("port: %s\n", d->PortNames[i]);
    printf (" default: %.1f\n", d->DefaultValues[i]);
    printf (" unit: %s\n", d->PortUnits[i]);

    if (d->PortValueEnum)
    {
      e = d->PortValueEnum[i];

      while (e && e->Label)
      {
        printf ("  value: %.2f = %s\n", e->Value, e->Label);
        ++e;
      }
    }
  }

i'm quite confident it's not too complicated a solution.

amicalement,
