Hi Tobie, All,

The intended behavior is similar to that of the accept attribute [accept]. To align more closely with that language, we could change the sentence to:


The capture attribute MAY be specified to provide user agents with a hint of a preferred capture control type for a file picker.


Or something along those lines -- feel free to suggest a better wording.

The draft dating back to 2010 talks about hinting in non-RFC terms, so it may well be. Unfortunately I'm unable to locate a reference.

All - Let us know if there are any concerns in changing the normative prose as outlined above.

Tobie - Thanks for the review!
