And is exactly my opinion...

I'm not convinced for reasons I explained yesterday.

Which is where the disagreement has arisen. The one thing I have seen that
convinces me that it could solve the problems is the proposal for
aria-describedat.

(I note in passing that there are other techniques that can be used to
present long descriptions which are applicable to a number of use cases.
However, these do not meet the set of real-world requirements I see which
longdesc does).

In case we can get consensus on such an approach, I'll draft an extension
spec.

I believe it is a compromise. But it is one I could live with.
