	Why not 1 and 2? That's what our web application here is doing. We
use XML because there has to be different levels of processing done on the
information stored in the XML. It's highly structured data, so we could have
chosen an object database, but i hate making purchase requests, and so XML
seemed like a good option. That and we needed to access the data from
different platforms and languages (Linux, NT, Perl, VBScript, Java).

	I developed a solution that allows us to easily edit the XML in a
HTML form, and it automatically generates structured XML on the back end -
this XML is totally based on the form - there's no processing going on to
create structure when processing a form.

	Currently these solutions are all in Perl, but they are implemented
on top of the raw expat API so they should convert easily to other
languages.
