Yes, we need to play nice with format().
I think this will require adding a method to the xml class.
The first thing to do is write the method in python.

Would this work?

     def format(self, *args, **kwargs):
         quoted_args = tuple(_quote_wrap(arg for arg in args))
         quoted_kwargs = _xml_quote_wrapper(x)
         return xml(unicode_str.format(self, *quoted_args,
**quoted_kwargs))
