Given this addresses Emmanuel’s concern, I added the following to the spec:


When the capture attribute is specified, the user agent MUST NOT save the captured media to any data storage, local or remote.


When scripts gain access to the files selected from the file picker (represented by a FileList object), they can use various mechanisms to store the captured media. These mechanisms are out of scope for this specification.


See the ED [1] and diff [2].

A note regarding testability: this assertion must be manually tested.

All - please let me know if you have concerns with the suggested change.
