According to the schema, all p:output (as well as p:input, p:option and p:variable) elements must precede the sub-pipeline. In this sense, nor Calumet nor Calabash are correct: they should both should reject the pipeline because it is not valid. Calumet does not validate the pipeline at the moment (and I think nor does Calabash). Calumet is quite forgiving in this respect and can deal with some out-of-order XProc elements - which, depending on your view, may or may not be a good thing. Calabash seems to be a bit more strict. Hope this helps. Regards, Vojtech -- Vojtech Toman Principal Software Engineer EMC Corporation toman_vojtech@emc.com http://developer.emc.com/xmltech
