You continue to make assumptions about the intention of my  
hypothetical example. I specifically said aria-describedby provides  
equivalent, not identical functionality of longdesc.

I grow weary of this exchange. You overlooked the entire point of the  
hypothesis to nitpick on details of little consequence. Nothing in the  
definition for @longdesc says it has to link to a raw text resource  
nor that it has to link to a resource that *only* includes the textual  
variant of the chart. As you keep repeating, it's just a URI. I'd  
argue that a URI to an HTML version of the long description plus a  
table of the full data set is more useful than a URI to just the long  
description. In the same spirit of universal design that allows access  
to everyone, I'd argue that showing a visible link to that long  
description resource (as in the code sample) is better than burying  
that URI in the longdesc attribute where almost no one can get at it.
