I'm not sure what you mean - the HTML specifications versions going back to version 2.0 only specify levels H1 - H6 for headings, I can't find any reference to H0.
Below are the links to the specifications that I normally use & also a good alround reference site for both HTML & CSS, which highlights changes & peculiarities for the main browsers.
