[Commentor] LC-2635 Michael Cooper (archived comment) [Working Group decision] No change needed, addressed by the following normative prose: "The capture attribute's invalid value default and missing value default is the File Upload state." [Commentor reply] yes [Comment] 
The Protocols and Formats Working Group took a quick look at the HTML Media Capture specification http://www.w3.org/TR/2012/WD-html-media-capture-20120712/. In a teleconference discussion, minuted at https://www.w3.org/2012/07/18-pf-minutes.html, we had the following comments: What happens if the requested device is not present on the system? People with disabilities may have a different sub-set of devices available than mainstream users. We suggest the specification state explicitly that the user agent should fall back to a standard file upload widget in this situation.
