lang rule checks that a lang attribute on the <html> is a valid IETF's BCP 47 language tag and doesn't check whether <html> has lang attribute or not, but the document says <html> fails for this rule.
html-has-lang document says:
This rule is largely superseded by the lang rule
so should we fix the implementation of lang rule to check html-has-lang rule in addition to lang validation? or should we remove the example of <html> from lang rule document?
