[ID] 64 [Status] Closed [Commenter] Neil King [Location] Step 4a [Suggested Change] "It is strongly recommended to also involve real users during this process.... Whilst we completely agree with this and conduct 'technical' testing with end users during WCAG evaluations, it is no substitute for formal usability testing. 'Practical' accessibility issues are just as important as 'technical' accessibility issues but may be disregarded when assessed in the context of a technical evaluation as they do not always directly map to WCAG 2.0." [Resolution] Resolution: Section rewritten. Rationale: Provides more guidance on how to evaluate content using WCAG 2.0 and its accompanying document. [Rationale] 
"We all interact with websites using different browsers, different ATs and different approaches. Determining the true nature of an accessibility issue when involving users is not as straightforward as merely asking them what they believe is the issue, or reporting on general observations as with mainstream users. To undertake comprehensive formal usability testing for accessibility we believe there is a real requirement to understand user experience, technical accessibility and how ATs are used and their capabilities; it is rare you find people with all of these skills and experience."
