[Commentor] LC-262 Ian Jacobs [Working Group decision] In the document we refer to Techniques and MobileOK which are currently being written. We can also imagine adaptation guidelines but we are not sure of the exact course. There's also a new User Agent test initiative but it hasn't started yet so we can't reference it. [Commentor reply] yes [Comment] 
A very important feature of the WAI Guidelines is that they work together to identify different responsibilities among authors, user agent designers, format designers, and authoring tool designers. WCAG does not hold up well in some cases when browsers don't take advantage of features that authors expect to be supported. Does the MWI BP WG plan to produce other guidelines than these content guidelines?
