/**
 * 
 * The WingTransformer is a simple framework for dealing with DSpace based SAX
 * events. The implementing class is responsible for catching the appropriate
 * events and filtering them into these method calls. This allows implementors
 * to have easy access to the document without dealing with the messiness of the
 * SAX event system.
 * 
 * If the implementing class needs to insert anything into the document they
 * these methods should be implemented such that they insert the correct data
 * into the appropriate places
