Well, it's widely agreed upon that the HTML Working Group really exists
just in some alternate reality; otherwise there is not really a good
reason for why all their specs are written in some crazy moon language.
http://www.mirrorproject.com/show-image.mirror?id=15043 has a recently
discovered photo of their real from the outside. Here in particular:

Well, I've no remote idea what this could possibly mean, there's also
a number of normative references that are relevant here, HTML 4 for
example. All these specs have myriads of known issues, I'd rather not
discuss based upon those...

Very odd indeed! Hixie's Terrifying Markup Language 5 might solve one
problem or another here though.

Well, you just can't tell the difference, since in order to test this
you'd have to create invalid HTML and the HTML WG violently refuses to
say anything about documents that don't validate to their crazy moon
schemas...
