I don't think that I misunderstood at all.
I agree that XML data-typing could be a very difficult problem.
Especially if we insist on making it so. But I think that
rewards are potentially much greater than you are allowing.
And I think that we can take small steps toward data nirvanna
-- I think that the greatest danger lies in the belief that
the importance of an ideal or complete solution should hold up
the next reasonable step.

Well, reasonable people can disagree, but I wonder why in this case.

Well, I qualify only inasmuch as English is one of the languages
which I read/write/speak. So, that dart seems to have missed
me as a target -- 404. I am not interested in a datatyping solution
that is only usable by db or Perl hackers. See SOX.
