I think it would be very interesting to have a CA that would execute an XSLT against an XML file. XSLT is a general-purpose language for transforming XML. It would be possible to express a whole slew of changes in a single XSLT script. Although XSLT is verbose, it's not as verbose as a bunch of XmlConfig elements ;) It would also be possible to conditionnally modify certain elements of the XML file (eg, "update the connection string, but only if it hasn't changed since installation").
Admittedly, this is a completely different route from your "xml diff" approach... would be useful though.
