how do you handle a client writing NaN to an analog record (which

Hm...

I would say, analog records are numerical, so setting it to not-a-number

should make the record undefined, setting the severity to INVALID (3.14)

or UDFS (3.15).

Would that match your idea?

Driving the record output could then configured in the regular way,

using IVOA/IVOV.

What do you think? Would that resolve yours and Götz' concerns?
