commonj.sdo.helper.XMLDocument
3.org/2001/XMLSchema"> Upon loading this XMLDocument: DataObject is an instance of Type PurchaseOrderType. RootElementURI is null because the XSD has no targetNamespace URI. RootElementName is purchaseOrder. Encoding is null because the document did not specify an encoding. XMLDeclaration is true because the document contained an XML declaration. XMLVersion is 1.0 SchemaLocation and noNamespaceSchemaLocation are null because they are not specified in the document. When saving the root element, if the type of the root dataObject is not the type of global element specified by rootElementURI and rootElementName, or if a global element does not exist for rootElementURI and rootElementName, then an xsi:type declaration is written to record the root DataObject's Type. When loading the root element and an xsi:type declaration is found it is used as the type of the root DataObject. In this case, if validation is not being performed, it is not an error if the rootElementName is not a global element.
