/**
 * Note that this is NOT a generic binding registry for users' binding; this is
 * a registry that is used internally just to manage binding between
 * XBeans for BindingTypes and BindingType wrapper classes.  The reason
 * for this mechanism is that XMLBeans binding is NOT YET powerful enough
 * to bind the various kinds of BindingTypes directly to schema yet.
 * 
 * However, in the future, we hope to make it powerful enough to do so,
 * so that most of the hand-coded binding betwen Java and XML can go away.
 * This class, and all the mechanisms that use it, should go away too.
