Re: Issue-742: Proposal aria-destination

The use case for having destination semantics to drive a consistent UI is
clear for coga.

The issue is which semantic values for destination can be clearly
articulated in time for ARIA 1.1. They indeed need to have clear use cases
and definitions for the values.

The DPUB ARIA have clear use cases for the aria-destination values that
came out of EPUB structural semantics and authoring. That only includes 4-5
discreet tokens. If the coga folks could articulate some values as a start
that meeti above for ARIA 1.1 they can continue to develop them post ARIA
1.1 for later inclusion.

Yes. I actually checked, and meant to be more explicit, as I was for some
of the rel values that ahd been proposed for HTML4 and not taken up at the
time.

But that's a decision, in part based on little interest in implementation,
presumably in turn based on no compelling use case.

If DPub or COGA or anyone else want to make things into standards and ship
them, we get use cases, requirements, and presumably implementation
commitment (without that, dreaming up ideas is just a pleasant pastime
anyway).

Attributes have been removed, and then reinstated, before now, based on
compelling use cases, a sense that a new thing of the same name isn't an
improvement, and demonstrated implementation uptake.
