I agree with the name change to NXpositioner.
I think it would be useful to have limits, should we have the soft
and/or hard limits ? And how should they be represented ? E.g.
Any ideas ?
I think that the units are ok as an attribute of the value.

I agree with the renaming. It is more generic that way.
I would be inclined to specify the NXpositioner a bit more like adding
limits, units. What do you and Stuart (the current proposer of NXmotor)
and the rest think ?
Currently the spec converter we have written converts a spec motor to a
single NXdata value but I don't find this very good because we have lost
the information that it is a positioner.
