WCAG Formalization with W3C Techniques [chapter]

Vicente Luque Centeno, Carlos Delgado Kloos, Martin Gaedke, Martin Nussbaumer
2005 Lecture Notes in Computer Science  
We present a comparison of some of them and propose some W3C techniques for expressing these constraints. Using W3C technologies, the evaluation cost can be clearly minimized.  ...  WCAG Evaluability Several rules can not be evaluated automatically by a program with an acceptable degree of trust because they require human judgement.  ...  As a result, tools really implement their own set of constraints which are based on the original from W3C, but having important differences from each other that result on different evaluation results,  ...
