Accessible annotations for SVG and  canvas seem to be a bit different.

SVG has a great deal of built in items for accessibility and many uses of SVG should use those features. They are not as widely adopted as we would like, but plenty of work has gone into the accessibility features.

However, an annotation for accessibility may still be useful. For example, a 3D model might provide a better mechanism for explaining the concepts intended to be conveyed in the SVG.

For canvas, one or more of the elements detailed in the Diagrammar  content model could be used in the annotation. I expect a textual description would be the most common use, but tactile graphics with  accompanying explanation of how to explore the tactile (tour) might be selected.

At any rate, the EPUB may meet the baseline for accessibility, but for some disability groups more would be needed.

It would be difficult for a publisher to put in everything that might be needed in the wild, and a DSSO office or an organization doing enhancements could create the additional information and of course deliver the enhancements through annotations.

George - can you comment on how this would relate to accessibility for SVG or Canvas?
