you're the first to do anything with it. just so you know.

the port name.

it was imagined that this is up to the particular widget to handle in
the "right way". i would rarely (if ever) use a knob widget that
didn't include a numeric display/input field as well, for example. i
don't consider the decision on what type of widget to use to be based
on the required precision: all controllers should (must?) be capable
of arbitrary precision.
however, i would agree that a "numinput" type as an explicit choice by
the GUI designer might not be a bad addition.
just keep in mind that nothing, absolutely nothing, has happened with
the LADSPA XML GUI proposal for at least 18 months, perhaps
longer. there are no plugins with GUIs written using the DTD.
