 A ''binding scheme'' associates some data types with a unique binding. The mapping of types to bindings is bijective, there is one binding for each type and vice-versa.
-<code>GenericBindingScheme</code> is a scheme that provides a fully implementing mutable binding for all data types.
+<code>DefaultBindingScheme</code> is a scheme that converts any datatype to a binding. It prefers java.lang.X primitives.
 The Class mapping for each type is listed below.
