Don't discount the power of abstraction!!! :)

XML is being abused as it is perceived to be the panacea of computing.
XML SHOULD be used to interchange information between systems so that
they can readily parse the structure (converting and/or using it as they
choose). For that reason I believe XML is a wonderful thing (not
counting the issue about structural reasoning). It is NOT meant to be
readable (configuration), nor does it perform when used as a database
(persist).
