If you want a visible description, make it visible and point at it with
aria-describedby.

(Requiring sighted keyboard users to use a secondary action on a control just
to get additional explanation seems like terrible UI by the way.)

Subject to implementation.

Mozilla, Microsoft, and Apple seem uninterested in adding default UI for
@longdesc even for images in their browsers, so I'm not holding my breath.

I don't get how @longdesc would help here given the target of @longdesc would
be outside the table too.
