Yes it is very material to the longdesc function but a sidebar to
Steve's  code example of basically:

<details>
<summary>Image</summary>
Long Description.
</details>

If that could work without a disclosure triangle or any visual
indication of a long description being present and without any
JavaScript or CSS hacka, it might work for an in-page longdesc.

But @longdesc already does that. And @longdesc does it out of page
too. We need both.

Best Regards,
Laura
