Good points - perhaps UBL users could be furnished with one or more stylesheets that would do the trick? They could download these from the UBL site, perhaps - or perhaps the stylesheets could be "custom generated" through user entry into a simple form from the UBL site into which the user enters information regarding their code list extensions, and out pops a tailored stylesheet that could be inserted into the processing stream between them and their trading partners.
