In the current framework, while there are success criteria there are no  
normative explanations of how they apply to given technologies. Instead,  
understanding WCAG 2.0 has been made an informative document.

This is inappropriate to ensure interoperability of tools and content.  
This has been a major problem with the implementation of WCAG 1.0, where  
important questions of interpretation (such as "are tables OK for  
layout?", "do all user agents identify form fields without default text in  
them?", "is it OK to rely on javascript?", "are px units OK for layout?"  
among others) have gone unanswered for many years leading to a major  
breakdown in interoperability between tools, services, and content itself.

I propose that the information be made available in a normative document.  
The process requirements for publishing such a document would seem to be  
very lightweight in the context of how long it takes the WCAG group to  
determine necessary changes, and this will at least ensure that an  
authorative answer becomes available for issues which arise.
