Unsure whether this inquiry is for schema to java or java to schema binding.
JAXB 2.0 schema to java binding of the above binds to
javax.xml.datatype.XMLGregorianCalendar.
(See Table 6-1 in S 6.2.2. in JAXB 2.0 specification) That binding
differentiates whether a
field within a xsd:date was specifically set or undefined. For your
example,
it would remember that all fields not having to do with xs:date are not set
(javax.xml.datatype.DatatypeConstants.FIELD_UNDEFINED) and they would
not be marshalled out.

For JAXB 2.0, Java to schema binds java.lang.Date to xsd:dateTime.
For a short term work around, could you try XMLGregorianCalendar
instead of Date.
This class was created to assist in preserving the XML calendar values
more precisely
than binding to java builtin calendar types.
Following is way to create an instance in Java that behaves as you desire:
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;
DatatypeFactory df = DatatypeFactory.newInstance();
// create xsd:date instance 1975-06-15
XMLGregorianCalendar dob =.df.newXMLGregorianCalendarDate(1975, 6, 15,
javax.xml.datatype.DatatypeConstants.FIELD_UNDEFINED).
If unmarshalling an xml document into XMLGregorianCalendar field, the
class' constructor remembers which fields where set or not.
Documented in the public review for the specification but not
implemented in RI yet, the above
field could be annotated with @XmlSchemaType(name="date") to map
java.lang.Date to xsd:date.
By default, JAXB 2.0 maps java.lang.Date to XMLGregorianCalendar.
