Hi all,
	I want to create Data with value which is a ShapeNode instead of String content. How can I do it ?
	Sample:
	<data key="d0">
	    <y:ShapeNode>
	        <y:NodeLabel>Node Label</y:NodeLabel>
	        <y:Shape type="circle"/>
	        <y:Fill color="#00FF00" transparent="false"/>
	        <y:Geometry height="10" width="10" x="0" y="0"/>
	    </y:ShapeNode>
	</data>
	Currently I tried to generate pojo classes from ygraphml.xsd schema by jaxb (jxc) then use those classes to create graphml file. Look into the class DataType, I just see it support method to set String content only.
	@XmlAccessorType(XmlAccessType.FIELD)
	@XmlType(name = "data.type", namespace = "http://graphml.graphdrawing.org/xmlns")
	public class DataType
	    extends DataExtensionType
	....
	@XmlAccessorType(XmlAccessType.FIELD)
	@XmlType(name = "data-extension.type", namespace = "http://graphml.graphdrawing.org/xmlns")
	@XmlSeeAlso({
	    DefaultType.class,
	    DataType.class
	})
	public class DataExtensionType
	    extends OriginalDataExtensionType
	....
	 
	public class OriginalDataExtensionType {
	
	    @XmlValue
	    protected String content;
	 
	Therefore I cannot set ShapeNode as value of DataType.
