When images are included on a page, the srcset attribute is included in the <img> tag. This is not allowed in HTML5. http://en.wikipedia.org/wiki/User:Gadget850/srcset http://validator.w3.org/check?uri=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FUser%3AGadget850%2Fsrcset http://dev.w3.org/html5/spec-author-view/the-img-element.html#the-img-element
It looks like this was intentional: Gerrit change #24115 CCing Brion.
srcset is still new in the draft spec and probably hasn't made its way to the validator yet.
Is this causing any problems with browsers which aren't aware of srcset? If not I suggest WONTFIX.
Here's the live draft spec, which does include srcset: http://www.whatwg.org/specs/web-apps/current-work/multipage/embedded-content-1.html#the-img-element

I emailed the validator folks and documented the issue.
(In reply to comment #5) > => Close this ticket as INVALID as per last comment? I agree.
