/*
* The reason this function exists is to provide compatibility for ExceptionDataContract to utilize ClassDataContract for deserialization.
* In order for ExceptionDataContract to deserialize using ClassDataContract the xml elements corresponding to private fields need
* to have their name replaced with the name of the private field they map to.
* Example: Message ---replaced to--> _message
*
* Currently this method utilizes a custom created class entitled ExceptionXmlParser that sits alongside the ExceptionDataContract
* The ExceptionXmlParser reads the xml string passed to it exchanges any element names that are presented in the name map
* in its constructor.
*
* The ExceptionXmlParser also gives each nested element the proper namespace for the given exception being deserialized.
* The ClassDataContract needs an exact match on the element name and the namespace in order to deserialize the value, because not all serialization
* explicitly inserts the xmlnamespace of nested objects, the exception xml parser handles this.
