Yes, there is a need for this in the spec, with NamespaceHandlers.  The 
current spec doesn't provide any helper classes for doing the parse() 
and decorate() calls on NamespaceHandler, so it's necessary to to write 
your own implementation classes for the reflection classes.  This means 
the extender implementation will be receiving back different 
implementations of these classes after a call.  Since we're likely to 
want to hang additional references and implement additional methods in 
the metadata implementations, a deep copy of modified metadata seemed 
like the simplest solution.
