FWIW, this change can be seen as merely a consequence of ARIA itself. Because ARIA says that @hidden elements will be revealed if e.g. aria-describedby points to it. I guess it should not affect the @longdesc Change Proposal that ARIA operates this way. Note that @aria-describedby makes no difference between hidden via @hidden and hidden via CSS display:none. And note that links, including @longdesc links, could - conformingly - be used to point to sections that have been hidden via CSS display:none. With the CSS :target selector, they could be revealed. Thus, it is still possible - despite this change - to use @longdesc in order to link to hidden sections, as long as the section has been hidden via CSS. This would also be an advantage of using @longdesc: @longdesc is interactive, whereas e.g. @aria-describedby is not. -- Leif H Silli
