“Clearly identify changes in the natural language of a document's text and any text equivalents (e.g., captions).”

This is important for:

• Braille readers
• Multilingual speech synthesizers
• Appropriate use of machine translators

Visitors who are reading the document in Braille will be able to substitute appropriate control codes (markup) where language changes occur to ensure that the Braille translation software will generate the correct characters (e.g., accent marks).

Speech synthesizers that have multilingual capabilities will be able to generate the text with the proper pronunciation.

Users will be able to have unfamiliar languages translated by machine translators.

Note: This also increases the accessibility of the content to visitors who may not be literate in the primary language of the document.
