My report will tell the designer which guidelines are complied with and which not. Any third party can check my results using the same procedures.

This would avoid confusion between the techniques that the web-designer uses to create an accessible page and the processes we, as evaluators, use to check that the page is compliant (either by using a W3C technique, or some other technique).
