Hi Christian,
okay, I solved the mime type problem with a patch against Orbeon. I don't know if it's really a good idea, but it works for now. Back to the other problem, passing an XML document to a query.
Instead, we could introduce an <input/> element, the child of which would represent the element to be bound as context item. Would this be helpful?
So, what would the request look like? After all I also need to specify the xquery file somewhere.
Kind regards, Ralf
