Comments to "Permissions for Device API Access"

Re the "Permissions for Device API Access"

(1) For the File API, I suggest a change.

The text: ³In the Web browser environment, this permission is usually
granted implicitly once the File object has been created, after the user has
selected a file from a file picker.²

Should be: ³In the Web browser environment, this permission is usually
granted implicitly once the File object has been created, after the user has
selected a file from a file picker, and is retained for later access in the
same session.² 

This is the behavior of the Firefox implementation of the file API at least.
Repeated access to the file is granted for the session, i.e. the webapp can
access new versions of the same file, in essence watching it.

(2) Do we have a clear definition of ³session² that is consistent across
specs?

Thanks,
Bryan
