These articles were translated into German thanks to Gunnar Bittersmann.
This article is based on text that was originally published in the WG Note, Internationalization Best Practices: Specifying Language in XHTML & HTML Content. The Note will be updated in due course, at which time the material will be removed from the Note.
The article discusses some of the pros and cons for signalling the language of a page which a link points to, if that page is not in the same language as the current content. It also looks at how people have done this in the past using the hreflang attribute.
Because of its history, the article has not been through the normal review process, but comments can be sent using the feedback form.
A future version of the article may look at alternative approaches and implementations, such as those used for European languages.
