Hmm... I see a possible bug of the XMLSchema library here. The schemas are kept as XMLschema objects inside the AxisService and what happens in the XMLBeans databinding is that the schema object is serialized and fed into the XMLBeans schema compiler. XMLSchema serilialization may have a problem and the mentioned namespace prefix may be generated by XMLSchema
