DatatypeFactory
http://xml.apache.org/commons/components/external/: xml-commons provides an Apache-hosted set of DOM, SAX, and JAXP interfaces for use in other xml-based projects. Our hope is that we can standardize on both a common version and packaging scheme for these critical XML standards interfaces to make the lives of both our developers and users easier. The External Components portion of xml-commons contains interfaces that are defined by external standards organizations. For DOM, that's the W3C; for SAX it's David Megginson and sax.sourceforge.net; for JAXP it's Sun.

Factory that creates new javax.xml.datatype Objects that map XML to/from Java Objects.
newInstance() is used to create a new DatatypeFactory.
The following implementation resolution mechanisms are used in the following order:

    If the system property specified by DATATYPEFACTORY_PROPERTY, "javax.xml.datatype.DatatypeFactory", exists, a class with the name of the property's value is instantiated. Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException. 
    If the file ${JAVA_HOME}/lib/jaxp.properties exists, it is loaded in a Properties Object.
     The Properties Object  is then queried for the property as documented in the prior step
     and processed as documented in the prior step.
   
   
     The services resolution mechanism is used, e.g. META-INF/services/java.xml.datatype.DatatypeFactory. Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException. 
   
     The final mechanism is to attempt to instantiate the Class specified by DATATYPEFACTORY_IMPLEMENTATION_CLASS, "javax.xml.datatype.DatatypeFactoryImpl". Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException.

Since:	1.5
Throws:	DatatypeConfigurationException – If the implementation is not available or cannot be instantiated.
Returns:	New instance of a `DocumentBuilderFactory`
Params:	lexicalRepresentation – `String` representation of a `Duration`.
Throws:	IllegalArgumentException – If `lexicalRepresentation` is not a valid representation of a `Duration`. UnsupportedOperationException – If implementation cannot support requested values. NullPointerException – if `lexicalRepresentation` is `null`.
Returns:	New `Duration` created from parsing the `lexicalRepresentation`.
Params:	durationInMilliSeconds – Duration in milliseconds to create.
Returns:	New `Duration` representing `durationInMilliSeconds`.
Params:	isPositive – Set to `false` to create a negative duration. When the length of the duration is zero, this parameter will be ignored. years – of this `Duration` months – of this `Duration` days – of this `Duration` hours – of this `Duration` minutes – of this `Duration` seconds – of this `Duration`
Throws:	IllegalArgumentException – If values are not a valid representation of a `Duration`. UnsupportedOperationException – If implementation cannot support requested values.
Returns:	New `Duration` created from the specified values.
Params:	lexicalRepresentation – Lexical representation of a duration.
Throws:	IllegalArgumentException – If the given string does not conform to the aforementioned specification. UnsupportedOperationException – If implementation cannot support requested values. NullPointerException – If `lexicalRepresentation` is `null`.
Returns:	New `Duration` created using the specified `lexicalRepresentation`.
Params:	durationInMilliseconds – Milliseconds of `Duration` to create.
See Also:	* XQuery 1.0 and XPath 2.0 Data Model, xdt:dayTimeDuration
Returns:	New `Duration` created with the specified `durationInMilliseconds`.
Params:	cal – `java.util.GregorianCalendar` used to create `XMLGregorianCalendar`
Throws:	NullPointerException – If `cal` is `null`.
Returns:	`XMLGregorianCalendar` created from `java.util.GregorianCalendar`
Params:	year – of `XMLGregorianCalendar` to be created. month – of `XMLGregorianCalendar` to be created. day – of `XMLGregorianCalendar` to be created. hour – of `XMLGregorianCalendar` to be created. minute – of `XMLGregorianCalendar` to be created. second – of `XMLGregorianCalendar` to be created. fractionalSecond – of `XMLGregorianCalendar` to be created. timezone – of `XMLGregorianCalendar` to be created.
Throws:	IllegalArgumentException – If any individual parameter's value is outside the maximum value constraint for the field as determined by the Date/Time Data Mapping table in `XMLGregorianCalendar` or if the composite values constitute an invalid `XMLGregorianCalendar` instance as determined by `XMLGregorianCalendar.isValid()`.
Returns:	`XMLGregorianCalendar` created from specified values.
Params:	hours – number of hours minutes – number of minutes seconds – number of seconds timezone – offset in minutes. `DatatypeConstants.FIELD_UNDEFINED` indicates optional field is not set.
Throws:	IllegalArgumentException – If any individual parameter's value is outside the maximum value constraint for the field as determined by the Date/Time Data Mapping table in `XMLGregorianCalendar` or if the composite values constitute an invalid `XMLGregorianCalendar` instance as determined by `XMLGregorianCalendar.isValid()`.
See Also:	DatatypeConstants.FIELD_UNDEFINED
Returns:	`XMLGregorianCalendar` created from parameter values.
