How to Fix the Problem

Identify the default language of a document by providing the lang and/or xml:lang attribute on the html element. In HTML documents use the lang attribute, while XHTML 1.0 allows both lang and xml:lang attributes, and XHTML 1.1 and above allows only xml:lang.

The Algorithm, in Simple Terms

Engine checks whether the document uses a lang or xml-lang attribute

Why Is it Important?

The objective of this technique is to identify the default language of a document by providing the lang and/or xml:lang attribute on the html element.
Identifying the language of the document is important for a number of reasons:
It allows braille translation software to adapt accordingly.
Speech synthesizers that support multiple languages will be able to speak the text in the appropriate accent with proper pronunciation.

Code Example

<blockquote xml:lang="en">

  <p>text

  </p>
