In fact, you can do it without resorting to ANY; you could also type
the attributes much more closely as well. There is already existing
software that will take a stab at it for you.
The original point, though, was that by definition a document is not
well-formed if it cannot be described by a DTD, not that the absence
of a DTD (or other schema) is insignificant.
