     I can't think of any.  You can certainly navigate the DOM without
foreknowledge of the tag names, but that won't tell you what to do
with each tag.  That is, there's nothing in the XML itself to tell you
to count the number of `person' tags, nor to print "Last Name : " before
the content of each `last' tag.  For that matter, there's nothing in
the XML that tells your program to ignore the `citizenship' tags.

     To put it another way: The XML data doesn't know which parts of
itself your program might be interested in, nor what your program
should do with them.  It's up to your program to know these things.
