[Commentor] LC-373 Bruno von Niman (ANEC W3C) on behalf of ANEC [Working Group decision] We have removed the section on usability. [Commentor reply] no reply from commenter [Comment] 
Chapter 1.3.2, Usability: - There are more than three aspects of mobile usability but there are three aspects of mobile Web usability (add “Web”). - The relation between these aspects should be described in detail (not only their individual characteristics). This description should include accessibility. - Site usability is not only about effectiveness (see definition of Usability).
