OK Sylvia, this sounds like a bug in JAXB Intros re how it supports @XmlAttribute. Would you mind creating a JIRA for this and attaching your original artifacts so I can have a look at it. Re examples etc... if you haven't done it already, check out the unit tests. Thanks for trying this stuff out and giving some feedback :-) Regards, T.
