Show me a better way that doesn't require prior knowledge of the XML format.

That method appears to require an a-priori schema.  If I have that I don't 
need the sender to tell me somethings an int.  I already know that.  (I do 
have to check the right format.)

And as I understand it, the approach described is far from the norm anyway, 
and thus only peripherally relevant.

So they send you a million byte string instead, and call it a string!  They 
can still DoS you.  The sender being able to say something's a number 
doesn't help with this.
