One other question: Is it a true statement that the JAXB Intros config: <Field name="value"> | <XmlAttribute name="value" required="true" /> | </Field> should be equivalent to the use of the @XmlAttribute tag annotation in the code as follows? @XmlAttribute private double value; If not what is the proper way to reproduce the effects of using the @XmlAttribute in a JaxbIntros config file?
