 /**
  * An interface to define classes that encapsulate access to both dictionary metadata and object field values, for example, by reflection
  * and introspection, for the purpose of performing validation against constraints defined in the DictionaryValidationService implementation. 
  * 
  * Practically speaking, this interface should only need to be implemented by a small number of classes. The two major use cases are for 
  * (1) a dictionary object with members 
  * (2) a specific member of a dictionary object
  * 
  * In the first case, implementing classes should provide access to all underlying members of the object via reflection or some other mechanism. 
  * In the second case, implementing classes only need to provide access to the value associated with that specific member, and constraints
  * requiring access to additional members will be skipped.
