It may be interesting, but it's factually incorrect. I did read the whole thing,
but almost stopped when I read:

There is no requirement for an XML document to be valid.

... except that's not a valid XML declaration - XML must be lower case in the
declaration.

Validation is concerned with the structure of the documents, not the semantics of
the contents. A paragraph that contains no characters is equally valid to one that
fully explains macadamia nut farming.

These three clangers were on the first page. If you're looking for generally sound

Dan, just not a great article.
