A page with content in British English. The xml:lang attribute on the html element contains the value ("en-UK"), which is not correct for British English ("en-GB"); the lang attribute contains the language and subcode for American English ("en-US"). Correct language codes and contradictory (and incorrect) subcodes for content in British English Christophe.Strobbe@esat.kuleuven.be en Copyright BenToWeb 2004-2007 2005-09-02 draft Specifying the language of content: the lang attribute

This test case is intended to fail because the primary natural language is correctly defined but the language version information is contradictory and one of the language subcodes does not exist. Subcodes to identify versions of languages are not required but should be correct when they are used. However, tests may show that contradictory and even incorrect information on language versions is not confusing.

Can you determine the language and language version of the text?

The browser cannot find the primary language of the document.

The lang and xml:lang attributes in the html element contradict each other, and xml:lang="en-UK" does not contain a valid language code.

(In Mozilla 1.7.3, the lang attribute takes precedence over the xml:lang attribute, so the language is incorrectly identifed as American English.)
