It is pretty obvious that I am referring to the fact that XML is used by
many developers as an easy data storage which they put in and pull out data
and is handled without much fuzz by the parser ... it is just an easier way
of app developement. Is this very elegant ? ermmm ... no. But take into
consideration that XML is perfectly useable without DTD / XSD which requires
more knowledge of XML and the gain is (in this situation) minimal.

I sure hope that those financial institutions you talk about use secure
connections and heavy encryption for their communications and not depend no
DTD or XSD to filter out malicious parties.

I know of several places where folks are doing schema validation on *their
own output* as well as everywhere they get an incoming XML message.
Perhaps they are less sanguine than you are about bugs. Or more
realistic. :) They are also concerned about malicious parties introducing
These are mostly financial institutions. As some of them have some of my
