That would be valid, but I would expect that most people would not be as
conscientious as you might be.

It is not unavoidable, but likely.  It is possible to create a
schema-conforming document in Microsoft Notepad but the environment does
not help you stay on the straight and narrow path.

I would expect that the DTD would lead to the correct nesting of
elements but attributes with regexs and possibly things with enumerated
"type" attributes would be problematic.

What OS do you use?
