Basically - replace SQL with XML ?

Personally I'd like to see how a large database such as the UK NI
database could be 'stored' as XML. As far as I can see there has to be
some mapping between the 'dump' of the entire database as an XML file,
and a more compact and usable internal representation. I have the
current XML Schemas, but they leave as many holes as plugs, and just
define several possible ways of including all the same simple data ;)

I'm slowly getting my head around the XML 'datatypes' and building a
mapping I can work with, but I still haven't 'seen the light' on how
this INTENDED to work practically.
