Of course, that is OK if That's a good point. The intention actually was that the implementation defined IRIs must only be used for algorithms not defined be the XML Encryption specification. That would be the same extensibility mechanism as the XML Encryption specification defines itself. My proposal however does not make this clear. I will revise it in this regard.
