[Bug 28263] [webvtt] "valid" language tags [I18N-ISSUE-429]

https://www.w3.org/Bugs/Public/show_bug.cgi?id=28263

--- Comment #3 from Philip Jägenstedt <philipj@opera.com> ---
Oh, the purpose of the syntax is perhaps not clear. The syntax is only used for
defining validity, i.e. for someone trying to implement a validator. To
actually implement WebVTT one must follow the parsing section, which doesn't
use the syntax in any way at all. When parsing, there is no checking of the
format at all. This is also how HTML works: whatever is in the lang=""
attribute will end up in the DOM.

Would it have helped to have a big warning at the top of the syntax section
saying that it is only used for defining validity, not processing?
