The JAXB specification explicilty states that JAXB's unmarshalling process
does not, by default, include an XML document's validation beyond what is
absolutely necessary to come to grips with the instance document and to
produce a content tree (like traditional DOM and SAX parsers).
Hence, simply dropping a value that cannot be bound to a Java enum constant
is the simple solution for the conflict you describe.
To validate against an XML schema, use the technique described in the
javadoc.
