Precisely.  I have a hard time figuring out why people who want named 
typing find XML exciting at all - it seems like a horribly inefficient 
approach for such things, with its own inconveniently incompatible 
markup-based notions of structures and labels.

Note that I still believe that XML is extremely useful for data.  I simply 
believe that the approaches and expectations surrounding that data have to 
adapt to XML rather than forcing themselves into XML.
