I'm not sure, but in writing an info provider I have to code something
... the options are to print nothing, to print a Key but not a Value, or
to print a Key with Value=UNDEFINEDVALUE. At the moment I can't do the
second one because the schema doesn't allow it, so I'm currently doing
the third one.

Not entirely, for example if you search for objects with an Extension
with a given Key regardless of the Value you'd get a different answer.
Whether there's a practical application is another matter ...
