Wanting to annotate element references is a perfectly reasonable aspiration, and is supported by W3C XML Schema. Unfortunately, of the two major XML Schema editors (XML Spy & TurboXML, in no particular order), the latter will trash element reference annotations if you open a Schema with it and then save that Schema. This is likely to cause confusion to a numerically significant proportion of UBL users if UBL uses element reference annotations. For my own part, I sometimes *fake* element reference annotations by annotating element definitions with information about their children. A little more indirect, but technically equivalent, and a little more robust. Alternatively, this is another area where Schema Adjuncts would be useful, if OASIS could bring that spec back from the dead. Cheers, Tony. ==== Anthony B.
