ISO Language Codes （语言代码）
The HTML lang attribute declares the language of a web page or only a part of a web page. It is used to help search engines and browsers. （HTML lang属性声明网页的语言或仅声明网页的一部分。它用于帮助搜索引擎和浏览器。）
W3C suggests to declare the primary language for every web page with the lang attribute inside the <html> tag.
See how to do it below:
<html lang="hy">
...
</html>
See how it must be in XHTML below:
<html xmlns="//www.w3cdoc.com/2014/xhtml" lang="en" xml:lang="en">

</html>
