Global lang-attribute validity (validity)

The global language attribute includes a valid language code such as for example, "en", "fr" or "fi" (ISO 639-1 Language Codes)


Invalid lang tag format:

This page uses lang="#1", which contains an invalid character. Since it does not follow the proper syntax for a language tag, the lang value is invalid and fails WCAG 3.1.1.

Note: Possible to automatically test. Automated tools can detect incorrectly formatted lang values that do not follow standard syntax rules.
