Hi Ian,

firstly thanks for your comments.

I agree. It's the same case here. Just like with "'a' elements that have an href attribute" we should also add "elements that have a draggable attribute set to true" to the list of elements that "should be made focusable by the user agent" at the bottom of section 7.5.1 of the spec. 

Btw. there is no information on what criteria the qualification is made for the elements in that "should" list in the spec. Maybe that should be added as well.

Fair enough. I thought it might come in handy some day to identify both draggable elements as well as elements that can "receive" drops without the use of scripting. E.g. in a parser or for search spiders to creater indexes for that faster...
