As long as the toString() for sql data outputs a date format that is
compatible with
XML Schema xs:date format. I have no idea if it is or not. JAXB provides
javax.xml.bind.DatatypeConverter.parseDate()/printDate to assist in
converting between
traditional Java datatypes and XML Schema builtin datatypes.

As long as the xs:date format is compatible with the input format that
SqlDate.valueOf() is expecting. Otherwise, try
javax.xml.bind.DataTypeConverter.parseDate()
to get a Java Calendar object.
You also might want to look at javax.xml.datatypes.XMLGregorianCalendar.
It is a JAXP 1.3 addition to assist JAXB 2.0 with more comprehensive
date handling and functionality.

JAXB validation at unmarshal and marshal time is provided by JAXP 1.3
validation.
(using the setSchema(Schema) method). Full XML Schema validation is run
during unmarshal and marshal time.
