I know a guy whose job it was to deal with these variant structures. So
it does happen. But he considered it the worst part of his job. He hoped
to move to XML so that he could encourage producers to produce reliable
data by providing a schema.

I don't understand what you mean by that.

They can do real accounting instead of staring at mangled XML documents
trying to figure out why the elements are wrong. Or they can join the
support line and help people trying to send documents to make valid
ones.

Well, the tools are out there to do this. I don't think businesses will
deploy them in the way you want for a variety of reasons. Once you let
your business partners know that you will accept non-conforming junk,
what incentive is there for them to provide you with good data? I guess
you could bill them for ever order you process by hand...

If the XML community creates a new job description of "business document
markup fixer" then I think we'll have done the white-collar working
class a great disservice. A person who "helps" the computer to analyze
variant documents will be a component of the system in a very
dehumanizing sense. They will likely be expected to deliver
computer-like turnaround times and extremely high levels of accuracy.
