I have created a patch against 7.x-1.x-dev which adds the following accessibility enhancements:
- Syndicate feed icons now have meaningful alt text
- The links for syndicate feeds have meaningful title text, with the feeds name.
- Taxonomy term counts are now wrapped in a span with meaningful title text.
These enhancements were made as part of the accessibility reviews we have been carrying out for aGov.
Let me know what you think (patch to follow)!
