This is a "not-end" requirement. What I want to mean is that this should be considered for any new page you create that Student can access. Also should correct the old pages.

I will use the label Feature Design Notes to this cases

WCAG: 3.1.2

The human language of each passage or phrase in the content can be programmatically determined except for proper names, technical terms, words of indeterminate language, and words or phrases that have become part of the vernacular of the immediately surrounding text.

Examples

This example demonstrates the use of the lang attribute to define a quote written in German.

<blockquote lang="de">
  <p>
    Da dachte der Herr daran, ihn aus dem Futter zu schaffen,
    aber der Esel merkte, daß kein guter Wind wehte, lief fort
    und machte sich auf den Weg nach Bremen: dort, meinte er,
    könnte er ja Stadtmusikant werden.
  </p>
</blockquote>

A German phrase in an English sentence.

In the sentence, "He maintained that the DDR (German Democratic Republic) was just a 'Treppenwitz der Weltgeschichte'," the German phrase 'Treppenwitz der Weltgeschichte' is marked as German. Depending on the markup language, English may either be marked as the language for the entire document except where specified, or marked at the paragraph level. When a screen reader encounters the German phrase, it changes pronunciation rules from English to German to pronounce the word correctly.

Alternative language links

An HTML Web page includes links to versions of the page in other languages (e.g., Deutsch, Français, Nederlands, Castellano, etc.). The text of each link is the name of the language, in that language. The language of each link is indicated via a lang attribute.

"Podcast" used in a French sentence.

Because "podcast" is part of the vernacular of the immediately surrounding text in the following excerpt, "À l'occasion de l'exposition "Energie éternelle. 1500 ans d'art indien", le Palais des Beaux-Arts de Bruxelles a lancé son premier podcast. Vous pouvez télécharger ce podcast au format M4A et MP3," no indication of language change is required.

Tests Procedure

For each element in the document:

Check that the human language of the content of the element is the same as the inherited language for the element as specified in HTML 4.01, Inheritance of language codes

For each lang attribute in the document:

Check that the value of the lang attribute conforms to BCP 47: Tags for the Identification of Languages or its successor
Check that the language code matches the language of the content it applies to.

Expected Results: All checks above are true.
