Technologies and Features

Technologies are markup languages or data formats. If the technology is a markup language, “features” refers to elements and attributes.

XHTML™ 1.0 The Extensible HyperText Markup Language (Second Edition)

XHTML™ 1.0 The Extensible HyperText Markup Language (Second Edition)

Feature: lang (namespace: http://www.w3.org/1999/xhtml) .

Technical specification: Specifying the language of content: the lang attribute .

Test Data

Purpose

This test case is intended to fail because the default human 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.

Expert Guidance

This test case can be evaluated automatically when using a test tool with reliable automatic language recognition for British and American English, support for lang and xml:lang attributes and language tags.

Test Modes

Automatic evaluation.

TCDL Data

Rules

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.

Primary Rules

The test case fails the following success criterion at line 3, column 44: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#meaning-doc-lang-id.

The test case fails the following success criterion at line 3, column 61: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#meaning-doc-lang-id.

Functional Outcome

The browser cannot find the default human language of the document.

Technical Comment

The lang and xml:lang attributes in the html element contradict each other, and 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.)

This test case maps to technique H57: Using language attributes on the html element

Note that when both lang and xml:lang are specified, the value of xml:lang takes precedence: see "The lang and xml:lang Attributes" in the XHTML specification (http://www.w3.org/TR/xhtml1/#C_7).
