Interesting, the plot thickens. I do see a getContent() method
generated for ValueType that is of type Object rather than List. This
is independent of whether I use the mixed attribute or not. I do use
the following local bindings:
<jxb:bindings version="1.0"
xmlns:jxb="
http://java.sun.com/xml/ns/jaxb"
xmlns:xsd="
http://www.w3.org/2001/XMLSchema">
<jxb:bindings schemaLocation="xml-rpc.xsd" node="/xsd:schema">
<!-- Illustrate binding model group to content interfaces. -->
<jxb:globalBindings bindingStyle="modelGroupBinding"/>
<jxb:schemaBindings>
<jxb:package name="com.starbak.manage.rpc.xmlrpc.beans"/>
</jxb:schemaBindings>
</jxb:bindings>
</jxb:bindings>
in order to get the "isSet...()" methods on my choices. Could this be
interfering with the generation of the getContent() method that returns
the List? If so, I think this may be a bug.
