Updated article: Language tags in HTML and XML

Read the article

The section “Extension and private-use subtags” was updated to incorporate the new u extension, registered by the Unicode Consortium to add information about language or locale behavior. Editorial improvements were also added to the description of private use subtags in that section.

Translators should consider retranslating the section “Extension and private-use subtags”.
