There are a couple of minor changes to EWB which would significantly improve accessibility:
1. HTML element should specify the LANG attribute - every accessibility tool complains about this
2. Images should have an ALT tag - trivial to add and would help most sight challenged people
3. input elements chould have a placeholder - again trivial to add
It would be nice to have AREA tags, like NAV, but I realize this would be significantly more work to introduce.
