	//validation:
//	If a class contains a mapped property or field annotated with
//	@XmlValue annotation, then all other mapped fields or properties in the
//	class must be mapped to an XML attribute.







//if the class, subClass, derives from another XML-bound class, baseClass
//	directly or indirectly (other than java.lang.Object), then the subClass
//	must not contain a mapped property or field annotated with @XmlValue
//	annotation.

//The containing class must not extend another class (other than java.lang.Obect).



//If the type of the field or property is a collection type, then the
//	collection item type must map to a simple schema type. Examples:
//		// Examples (not exhaustive): Legal usage of @XmlValue
//		@XmlValue List<Integer> foo; // int maps to xs:int
//		@XmlValue String[] foo; // String maps to xs:string
//		@XmlValue List<Bar> foo; // only if Bar maps to a simple schema type



//	If the type of the field or property is not a collection type, then the type
//	of the property or field must map to a schema simple type.
