ARIA und Progressive Enhancement
Derek Featherstone über die Probleme mit ARIA und Progressive Enhancement:
The problem that we have right now is that ARIA is an all or nothing deal. And writing scripts that respect both an ARIA supported methodology and a non-ARIA methodology is going to be incredibly difficult, because we have no reliable way of knowing the status of a user agent’s support for ARIA—it depends on something we can’t detect: the right combination of browser, assistive technology, and full ARIA implementation.
Suddenly, our progressive enhancement stack has been broken. We can’t detect ARIA support in the browser and therefore can’t make wise decisions on how to provide the most appropriate keyboard access for ARIA and non-ARIA scenarios.
