Schemas aren't always present where people deal with namespaces. So
while people can check, in practice they don't always do it, and
sometimes they cannot or don't know how to.

In C++ or Perl or Python or Java, you simply get a compile-time error
telling you what's wrong, and there is no way around it. (Okay, in Perl
there *is* a way around it, but frankly, the people going it deserve all
the pain they're inflicting upon themselves.)

I can see another good reason here to put namespaces in the DTD - you
could get a compile-time error for your document. :-)
