  +    <p>For example the betwixt file could allow methods to be used in addition 
  +    to bean properties for mapping objects which are not beans. </p>
  +    <p>Also we could support the ContextExpresssion to allow a bean to change 
  +    how its child objects appear. e.g. a Customer object may contain a Map 
  +    property which might appear differently to an Order object which has a Map 
  +    property - depending on the types of the keys and values. So rather than 
  +    relying on Map.betwixt to decide, the Customer.betwixt could specify the XML 
  +    format for the Map object.</p>
  +    <p>Allow betwixt files to be specified explicitly on the Introspector. This 
  +    will allow a Customer.betwixt to be used on a FooBarCustomer bean and to 
  +    allow different views to be used on the same bean. Might also want to 
  +    consider the introspector searching base classes and interfaces so that 
  +    derived types can inherit their parents formatting.</p>

  +    closely as possible when finding betwixt files like the bean introspector 
  +    looks for BeanInfo classes.</td>
