class	ReferenceBindingReplacerVisitor This visitor class will traverse a language object tree, find any Reference objects, and replace them with the corresponding parsed Expression which is the Reference's binding.
class	XMLNodeMappingVisitor This visitor is able to map symbols based on the XML document model: given a symbol representing one of the nodes of the document which is mapped, this object will find the Symbol representing the relational element it is mapped to.
