So if the website has pages in different languages, there is no way to make this clear for screenreaders and search engines.

About `lang` attribute:
lang attribute is used to identify the language of text content on the web. This information helps search engines return language-specific results, and it is also used by screen readers that switch language profiles to provide the correct accent and pronunciation."
