I have to define a class attribute on the abstract mapping otherwise
the compile fails.
With the above binding xml file, I get the following when trying to
run the jibx compiler.

So I have a couple of questions really
1. What have I missed that's causing the above?
2. Should I be using an array, rather than a Collection type, if it's
going to contain subclasses; i.e. will they be mapped OK, once I get
past the first issue?

James
