Re: PFWG comments on HTML Media Capture ( LC-2636)

Thank you for your comment. The proposed addition addresses the concern
we raised, but we have an editorial "friendly amendment". Where the
addition says "... giving implicit consent ..." we suggest to replace
"implicit" with "explicit", or to drop that qualifier. While "implicit"
can mean "unreserved" it also can mean "implied, rather than expressly
stated", which conveys a different meaning than is probably intended.
The word "explicit" means "fully and clearly expressed or demonstrated"
and is probably the intent. If that is not, or if it still seems
confusing, it might be better just to drop the qualifier, which could
raise more questions than add clarity. Just saying "... giving consent
..." may be sufficient.

We hope you will take this edit to minimize ambiguity, but in any event
the PFWG formally accepts your disposition of comment LC-2636.
