Re: [niso-sts] Question regarding alternative and description text

["G. Ken Holman g.ken.holman@xxxxxxxxx" <niso-sts-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Rereading the documentation, I think I found the key phrase I was looking for:

  "non-visual element"

... found for both elements. So, I guess that is definitive that I 
have no rendering obligations outside of those used for assistive 
access, and so I conclude it must not contain normative content.

Although I am a bit worried when I read for <long-desc>:

  "... explains both the visual form of the chart
   and significance of its findings."

... because I would think "significance" borders on being normative. 
If the long description is to be assistive regarding an impairment 
preventing the visualization of a graphic or table or formula, any 
accompanying general text would/should already have normative 
significance for all readers and, therefore, should not be in 
assistive content that not all readers access.

Anyway ... I have my direction.

So I withdraw my question ... sorry for taking up the bandwidth.
