If we can agree on the behavior, I would be glad to write up a patch.
It seems to me that the simplest way to proceed would be for the code
that attempts to resolve character references (both named and numeric)
in attributes to be isolated in a single method. Subclasses that desire
different behavior (including the existing Python 2.4 and prior
behaviour) could simply override this method.
