the properties of the base class always appear before those of a derived
class, so I think you only need to say propOrder={"data"}.
And currently, the order properties show up in XML is the order they are
defined in the Java source code, so actually you don't have to write
propOrder at all (although there's a quite lengthy tricky issue behind this)

I think the current behavior is correct. I think requiring members of
the base type to be before those of the derived types is a reasonable
limitation, and I don't think you want to list all the base type
property names every time you define propOrder for a derived type.
How do you think?
