Rule n° 127 - Each language change is identified.

Goal

• Enable technical aids to correctly interpret content expressed in another language.
• Simplify the work of machine translation tools.
• Enable web crawlers to extract strings of characters in a given language.
• Improve the accessibility of content for people with disabilities.

Implementation

Use the lang attribute and the appropriate language code for all content with a different language from that of the current page. For example: <title lang="en">Open quality standards</title>

If the content with a different language is not already tagged by an element of the existing HTML structure (title, link, quote etc.), a specific element is then required (div or span) to specify the language of this element (with the exception of the content of the title element which cannot include internal markup.).

Control

In each page checked:

• Identify all the content written in a language other than the main language, including the content of the HTML attributes returned to the user (such as that of the alt attribute of images)
• Check that the language of this content is specified via a lang attribute put in the appropriate element by the change of language (title, link, list item) or inherited from a parent element.
