Related issue #535
About the section, visual indications are present to signal added roles and proposed additions. For example, for the button role ("combobox" is styled as an addition and "gridcell" as a proposed/candidate addition):
But :
- The markup caption at the beginning of the document is neither complete (missing states) nor accurate (same styling):
Note: the duplicated caption block even appears to be an error.
- Markup is not accessible to screen reader users (just visual styling).
One way of addressing this last problem: see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ins#accessibility.
