A blank (as in just XML declaration) sounds good to me.

Markus, I've been wondering about this too. My feeling is that we simply return an empty document (xml definition at top, but empty otherwise). I think defining a custom <NULL> or <NoMatches> element may be confusing because with no envelope, the message should be an instance of some schema other than TAPIR -- one that does not define <NULL> or <NoMatches>. I think the first approach (empty doc) is less likely to break clients. -Steve Döring, Markus wrote:

I found an unsolved problem in my pywrapper notes today regarding envelope-less operations. If I request a TAPIR GET service search operation which doesnt match any results, what should be returned? Without an envelope this would be an empty document without even a root! Should we turn on the envelope in this case? Or return something like <NULL> or <NoMatches> defined by the protocol?
