The lang attribute applies to almost every XHTML element. It specifies the language of the content within an element.

Mandatory XHTML Elements
强制XHTML元素
All XHTML documents must have a DOCTYPE declaration. The html, head and body elements must be present, and the title must be present inside the head element.
所有的XHTML文档都必须有一个DOCTYPE声名。html、head和body元素必须出现，并且title必须在head元素里

This is a minimum XHTML document template:
这是一个极小的XHTML文档模板

oes here>
http://www.w3.org/1999/xhtml">

Note: The xmlns attribute inside the tag is required in XHTML. However, the validator on w3.org does not complain when this attribute is missing in an XHTML document. This is because "xmlns=http://www.w3.org/1999/xhtml" is a fixed value and will be added to the tag even if you do not include it.
注意：XHTML文档要求xmlns属性出现在html标签中。然而，w3.org的校验器不会由于这个属性没有出现在你的XHTML文档中而报告错误。这是因为"xmlns=http://www.w3.org/1999/xhtml"是一个固定的值，即使你的文档里没有包含它，它也会自动加上的。
