PDF documents can certainly contain image descriptions, and the alt tag
in PDF should be used for that where alt-text is available.

Ibd consider formatting an image-description as a secondary caption in
PDF. After all, someone might be using a text reader on a PDF file.

What you are really asking is, "can i make this document unusable by
people I don't care about". Which isn't what i think you actually mean
to ask :-) but is the effect.

A paper rendering, however, could reasonably ignore alt-text and could
either ignore the long descriptions or put them in an appendix.
