Overriding a built in serializer/deserializer

[jd...@brunswickwdi.com]

Is there any way to override the serializer/deserializer for a built in 
type?   When I call the MapType method of the service class on a type that 
is an element, array, whatever.  it never calls my serializer.   Instead 
it uses the "built in" mapping.  My code works fine for user defined 
types. Any help is very appreciated.
