H45 should also mention how poorly supported longdesc is generally,
including in current browsers. Only Opera and iCab currently provide
direct access to longdesc links for all users.

Something along the lines of Steve Faulkner's message [1] to
HTML-A11Y-TF should be included in the support notes so authors are
aware of the current problems with using longdesc:

- Support for longdesc in browsers and AT is poor and has been so for
many years.

- Adding a longdesc without an alternative method of access to the
long description results in many users with disabilities being unable
to access the content or even being aware that the content is there.
