It sounds useful, but the interface need a bit more thought.
content_xml() here is just receiving a string - how does it know it's
meant to be a package-name?
Following the convension used for other methods, it would be something like:

    content_callback_xml => 'Myapp::FormFu::Content::return_string'

If HTML::FormFu::Attribute::mk_output_accessors() were extended to
provide the new methods
*_callback()
*_callback_xml()
*_callback_loc()
then anything that uses mk_output_accessors() to create methods would
benefit from it.

A patch for this would be welcome!

Cheers,
Carl
