These problems are not to do with a scalar version.  They are the result
of partial implementations, faulty implementations with large market
share, and designers who never read and understand source documents, so
fail to understand that certain things are deliberately not specified,
in order to allow different implementation approaches, but then expect
everyone else to follow the market leader.

The result is that a browser will typically be at an implementation
extension level in one area, CSS2 in another, CSS3 in yet another,
CSS1 elswhere, broken in places, technically compliant but constrained
by display technology in such a way as not to be able to meet designer
expectations, in places, etc.  There are no complete CSS 2 implementations,
and probably no complete CSS 2.1 ones.

Also, extremely few HTML documents have valid doctypes, and, for most
well formed HTML it is not possible to specify one because the browser
developers don't publish DTDs for their extensions, but most commercial
HTML uses those extensions.  That suggests that the presence of version
information would be so unreliable as to be useless.
