INTERNAL:

Purpose: A Subclass of Inheritance Policy to be used with XML Descriptors. If the class indicator field is an xsi:type, the value of that field may be a qualified type name. For example xsi:type="myns:my-type-name". Since any given XML document can use different prefixes for these namespaces, we must be able to find the class based on QName instead of just the string "myns:my-type-name".
