That is correct.

I don't think so. The simpler the solution the better.  Complexity
confuses and leads to errors. This is especially true when complexity
is imposed directly on run of the mill  authors/web designers. Build
on the success of alt for the SHORT description.

As an on-page or off-page LONG description, full semantics are
provided with longdesc. And as soon as ISSUE-30 is settled
successfully, it could be made available to <picture>. Or the picture
element could allow for semantic programmatically determinable in-page
rich text long description, if a description element was added to the

<img src="image.jpg" alt="text alternative">
<desc>structured rich text description with headings, lists, tables, etc.</desc>
