[Commentor] LC-410 Charles McCathieNevile on behalf of Opera Software [Comment] [This is a comment on Mobile Best Practices, but cc'ed to WCAG as a comment for them on text the are currently using] The wording "Ensure that perceivable structures within the content can be programatically determined", copied verbatim from the WCAG working draft, has proven to be very difficult to understand for the majority of the developers I have ased to comment on this draft (which is only a couple of dozen). Perhaps something more straightforward, like "use markup, properly" is simpler for a title, with the current title moved into the "what it means" session as a couple of sentences. cheers chaals [Commentor reply] no reply from commenter [Working Group decision] 
We have changed the wording to: "Use features of the markup language to indicate logical document structure."
