> If I leave out the [name="TransactionRecord"]  in the last element (so it becomes anonimous),
I get the following NullPointerException:

> ------------------------------------
> It seems a general bug - if you use anonymous elements, you'll get a NullPointerException
in the SchemaCompiler.
> My advice: NEVER EVER allow NullPointerExceptions! You can't even see at what line of
the WSDL the compiler failed.
> It took me quite some time to find the cause of this problem...
