Sc3 1 1 Html

Created by: Annika Nietzio

Description

This test checks that the primary language of the web content can be programmatically determined.

Background

• H57: Using language attributes on the html element
• eGovMon test for H57
• BCP 47: Tags for the Identification of Languages

Assumptions

• The comparison of language codes does not look for exact matches. Technique H57 states: “Use of the primary code is important for this technique.” which means that region subtags can be ignored in the comparison, i.e. “en-GB” is the same as “en”.
• This test checks the lang attribute of the html element. The xml:lang attribute is not taken into account because tests have shown, that xml:lang is ignored by screenreaders. (Both Jaws 15 with FF and IE and NVDA with FF go by lang attribute, xml:lang is ignored.) The xml:lang attribute is checked by a separate test: SC3-1-1-xml-lang.
