I was incorrect for stating that this was a short term workaround.
I just double checked that the time component of Date is not optional
and there is no
way to represent that the time component does not exist in
java.lang.Date. All java.lang.Date
instances represent a specific millisec in time. XMLGregorianCalendar
uses FIELD_UNDEFINED to represent its fields that are not set,
getting the results that you desire.
