 * 
 * 
 * When a definition registry processor is invoked type converters and registry processors have been already
 * been created. Hence, changing component definitions for these or any components referenced by them will have 
 * no effect.
 * 
 * Note: a processor that replaces existing component definitions with new ones should take care to copy
 * interceptors defined against the old component definition if appropriate
