I'm trying to find/generate an XML file for a CONTRL message with the segment UNH+000001+CONTRL:D:3:UN' The parser is looking for EDIFACTINTERCHANGE_CONTRL_3 which is not present and my attempts to generate one using the openedifact-un2xsd app have been unsuccessful as I cannot find the appropriate specification files. Do you know how I can obtain either the correct .XSD or the means by which I can generate one? Many thanks.
