[Bug 21565] Should it be an error to use @longdesc on presentational images? And/Or should it _affect_ the role of the image?

--- Comment #1 from Charles McCathieNevile <chaals@yandex-team.ru> ---
I don't think the presence or absence of a longdesc should be used as a
determinant of whether an image is presentational.

Use case for longdesc on presentational images:
Stock photography is often included in marketing content (such as home pages,
press releases, etc). It is typically decorative, and should have alt="" in
many cases. But adding an accurate longdesc allows the photo provider to make
their content more discoverable - the legitimate sense of advertising. It also
makes it possible to get a better sense of the design aesthetic without having
seen the image, which is useful to a range of different people.

I therefore think that having a longdesc on an image with alt="" should not be
a validation error.
