When containment is true, then DataObjects of that Type will appear as nested elements in an XML document.
When containment is false and the property's type is a DataObject, a URI reference
to the element containing the DataObject is used and an sdo:propertyType
declaration records the target type. Values in XML documents will be of the form
"#xpath" where the xpath is an SDO DataObject XPath subset. It is typical to
customize the declaration to IDREF if the target element has an attribute with type
customized to ID.
[TYPE.NAME] is the type of the element. If property.type.dataType is true,
[TYPE.NAME] is the name of the XSD built in SimpleType corresponding to
property.type, where the prefix is for the xsd namespace. Otherwise,
[TYPE.NAME] is property.type.name where the tns: prefix is determined by the
namespace declaration for the Type's URI.
