/**
* Reference to other schema components.
*
*
* There are mainly two different types of references. One is
* the direct reference, which is only possible when schema components
* are already available when references are made.
* The other is the lazy reference, which keeps references by names
* and later look for the component by name.
*
*
* This class defines interfaces that define the behavior of such
* references and classes that implement direct reference semantics.
