Re: Call for Review: HTML5 Image Description Extension (longdesc) Last Call

I have an additional suggestion that I believe would help the acceptance of this document within the general working group. Add an informative section detailing several of the many cases where it is inappropriate to use @longdesc. For example…

1. @longdesc is inappropriate when an EPUB footnote is sufficient.
2. @longdesc is inappropriate for Math. Use MathML instead.
3. @longdesc is inappropriate for SVG graphics. Make the SVG DOM accessible instead.
4. @longdesc is inappropriate for graphics of tabular data. Use an accessible table instead.

More examples at http://cookiecrook.com/longdesc/

These should probably be added to the WCAG 2.0 Techniques documents as well.
