Fully conforming to specifications
Fully conforming to specifications
ID: G192
Technology: general
Type: Technique
When to Use
This technique relates to all markup languages with specifications.
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
A page is created with care to make sure that all technologies are used according to specification. It is run through a validator and all identified errors are corrected. Specification requirements that can not be identified by validation are also checked and any failures are corrected.
Tests
Procedure
Check that all technologies are used according to specification.
While validators can be great tools for catching errors, they usually cannot catch all cases where content fails to fully conform to a specification.
