Also, the Babel aspect of XML means that you always do need to write a 
parser, if not of the XML itself but to transform the 
plucked-from-the-air schema and arbitrary choices of what is an 
attribute and what an element to the data structure you are using.

A key part of Microformats is converging the schemas so this becomes 
much less necessary.

Have a look at the Universal Feed Parsers 3000 test cases...
