Yang, First of all, this is a pretty rare corner case. Even if the global namespace wasn't null (for example, assume it's just "http://global";), your example is an SDO Type with two properties named "element1". The SDO spec says that if you have more than one property with the same name, the first one hides the others, so you wouldn't actually be able to change the second one, unless you add an aliasName.
The next thing about the spec is that the CS serialization of old values (ChangeSummary.Settings) isn't really valid XML anyway. It's just a partial fragment, of XML that represents the changed value(s) and a reference (sdo:ref) to the actual changed object. So, for this case, I'm not even sure whether or not the element name being serialized shouldn't actually be the SDO property name itself. For example, say we used the sdo:name annotation to rename the second element1 to "second1" then maybe the CS should actually look like this: <element1 ... > <second1 ... > There are really more questions then answers in the spec related to CS serialization format :-( With all that in mind, I would say that if you need to find out if a property maps to an XSD ref element, then you can always use EMF's ExtendedMetaData. But, I'd suggest not worrying too much about these corner cases yet. Just make note of them so that we can get them addressed in the spec. Thanks, Frank.
