Hi!

I notice that other implementations of OAI-PMH servers give an error when setSpec specified doesn't exist. For example:

+ set=foo on Koha (ByWaters) : List records anyway

+ set=foo on a Greenstone v2.82 : Return an error.

This behavior is expected? I shuld fill a bug?

Cheers,

Pablo

PS: BTW, with the use of <?xml-stylesheet tag > that response is much nicer than Koha one!
