/**

 * The DatatypeConverterInterface is for JAXB provider use only. A
 * JAXB provider must supply a class that implements this interface.
 * JAXB Providers are required to call the
 * {@link DatatypeConverter#setDatatypeConverter(DatatypeConverterInterface)
 * DatatypeConverter.setDatatypeConverter} api at
 * some point before the first marshal or unmarshal operation (perhaps during
 * the call to JAXBContext.newInstance).  This step is necessary to configure
 * the converter that should be used to perform the print and parse
 * functionality.  Calling this api repeatedly will have no effect - the
 * DatatypeConverter instance passed into the first invocation is the one that
 * will be used from then on.
 * </p>
 *
 * <p>
 * This interface defines the parse and print methods. There is one
 * parse and print method for each XML schema datatype specified in the
 * the default binding Table 5-1 in the JAXB specification.
 * </p>
 *
 * <p>
 * The parse and print methods defined here are invoked by the static parse
 * and print methods defined in the {@link DatatypeConverter DatatypeConverter}
 * class.
 * </p>
 *
 * <p>
 * A parse method for a XML schema datatype must be capable of converting any
 * lexical representation of the XML schema datatype ( specified by the
 * <a href="http://www.w3.org/TR/xmlschema-2/"> XML Schema Part2: Datatypes
 * specification</a> into a value in the value space of the XML schema datatype.
 * If an error is encountered during conversion, then an IllegalArgumentException
 * or a subclass of IllegalArgumentException must be thrown by the method.
 *
 * </p>
 *
 * <p>
 * A print method for a XML schema datatype can output any lexical
 * representation that is valid with respect to the XML schema datatype.
 * If an error is encountered during conversion, then an IllegalArgumentException,
 * or a subclass of IllegalArgumentException must be thrown by the method.
