/**
* JAXB-induced mapping between a Java class
* and an XML element declaration. A part of the compiler artifacts.
*
*
* To be precise, this is a mapping between two Java classes and an
* XML element declaration. There's one Java class/interface that
* represents the element, and there's another Java class/interface that
* represents the type of the element.
*
* The former is called "element representation" and the latter is called
* "type representation".
*
*
* The {@link Mapping} interface provides operation that lets the caller
* convert an instance of the element representation to that of the
* type representation or vice versa.
