Thanks for all the replies, that’s what I thought but it's always nice to have ammunition for the inevitable "Why do I have to do this" questions.

Subject: Re: [WebAIM] Html Lang code for page


I tracked a bunch of ways that lang is used on a page [1]:

• VoiceOver on iOS uses the attribute to auto-switche voices.

• VoiceOver can speak a particular language using a different accent when specified.

• Leaving out the lang attribute may require the user to manually switch to the correct language for proper pronunciation.

•JAWS uses it to load the correct phonetic engine / phonologic dictionary — Handy for sites with multiple languages.

• NVDA (Windows) uses it in the same way as VoiceOver and JAWS.

• When used in HTML that is used to form an ePub or Apple iBooks document, it affects how VoiceOver will read the book.

• Firefox, IE10, and Safari (as of a year ago) only support CSS hyphens:
auto when the lang attribute is set.

Frankly, I believe it should be on every page. Since it can be set in a global template, it should be a matter of setting it once and not worrying until you find a rare case where you have to override it (which is good).
