HTML 4.01, CSS 2.1, and the UTF-8 encoding aren't standards either. People still refer to them as standards all the time, because de facto, they are.

What they are is formally defined, so people can look at the definition to write implementations, unlike with Perl5. That is one of the things Perl6 aims to provide. For Perl5, this is not going to happen.
