SC4-1-1-accesskey

This test belongs to 4.1.1 Parsing.

Version 1

Description

This test checks accesskey attribute for all elements to have a unique value.

Background

• F17: Failure of Success Criterion 1.3.1 and 4.1.1 due to insufficient information in DOM to determine one-to-one relationships (e.g., between labels with same id) in HTML
• eGovMon test F17-1

Assumptions

• If the accesskey value has multiple characters the user agent picks the first character and ignores the rest. http://www.whatwg.org/specs/web-apps/current-work/multipage/interaction.html#the-accesskey-attribute
