I'm using a simple ExtendedMetaData 'name' on some of my
multiplicity-many attributes, so that the serialization uses the more
natural singular name instead of the plural. So you get something like this:
<child name="one"/>
<child name="two"/>
instead of
<children name="one"/>
<children name="two"/>
It works fine, except for those attributes that are part of an abstract
superclass. For example:
abstract ClassA{
List children
}
ClassB extends ClassA{
String someAttribute
}
I've annotated children with an ExtendedMetaData, but I still get
something like this:
<ClassB someAttribute="text">
<children name="one"/>
<children name="two"/>
</ClassB>
Have I overlooked something, or am I just out of luck trying to use this
ExtendedMetaData annotation on the attributes of abstract classes?

Thanks Ed,
I assumed it should work the way you described. My mistake was a
silly one. I had the annotation source as 'ExtendedMetaData' instead of
'http:///org/eclipse/emf/ecore/util/ExtendedMetaData'. I didn't notice
it right away since they display identically in the editor.
