Story: I as a blind or vision impaired student need structured and rich descriptions for infographics and other information rich images I find in STEM textbooks
Descriptions for infographics and other STEM related images require more than textual descriptions. They may need HTML tables, lists and links. This is the use case for aria-describedby and longdesc.
An advantage of longdesc and aria-describedat is that they support rich and structured descriptions as described above. However, the descriptions are not encapsulated within the image and thus may get separated, which makes it harder to share and reuse image descriptions.
- Both of these stories need the <desc> element in SVG to support rich HTML markup. This markup needs to be accessible to assistive technology.
