Yes - I should have added that I was one of the early UBL members back in 2001 (you had no way of knowing that).

Oh, I wasn't thinking centralized - let's think more broadly, as in distributed/federated.

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.
