Which has nothing to do with what we're discussing here. No software
system I've seen is smart enough to tell whether a particular problem
should be a caution or a warning in the face of a person mislabelling
the content. A DTD cannot tell if a writer has used a caution where a
warning is appropriate or vice versa. Similarly, a validator cannot
determine if a warning has been omitted where one is called for. It
can tell that a warning element is not present, but it has no way to
know that there should have been a warning in the first place.
