Most e-commerce players are going to use XML only for interchange;
despite the best efforts of self-proclaimed XML vendors, few real
players would be foolish enough to redesign all of their internal
around XML.

That means that you're going to get XML => proprietary internal
storage => XML, where the XML that comes out may or may not bear any
resemblance to the XML that goes in -- elements, attributes, PIs, and
even character data may come out completely transformed (or not at
all), because equivalence will be defined by something other than the
XML markup model.


All the best,


David
