/**
* <p><b>Purpose</b>: Represents an XML Document containing a tree of DataObjects.
*
* An example XMLDocument fragment is:
* <?xml version="1.0"?>
* <purchaseOrder orderDate="1999-10-20">
*
* created from this XML Schema fragment:
* <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
* <xsd:element name="purchaseOrder" type="PurchaseOrderType"/>
* <xsd:complexType name="PurchaseOrderType">
*
* 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.
