G192: Fully conforming to specifications

Applicability

This technique relates to all markup languages with specifications.

This technique relates to:

Description

When markup languages are used in a way that fully conforms to their specifications, all of the requirements in 4.1.1 are met. Therefore, while fully conforming to specifications is not required to conform to WCAG 2.0, it is a best practice and is sufficient to meet Success Criterion 4.1.1.

Examples

Tests

Procedure

  1. Check that all technologies are used according to specification.

Note: While validators can be great tools for catching errors, they usually cannot catch all cases where content fails to fully conform to a specification.

Expected Results

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.

Techniques are Informative

Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques.
