Accessibility/Planning

Q3 goals:

1. Provide accessibility support for existing and new HTML5 input controls
2. Detect accessibility support requirements at run-time to inform dynamic performance decisions.
3. Improve life cycle management of our accessibility node and frame proxy objects (nsIAccessible).

Measuring:

1. Mochitest coverage + Marco screen reader testing. Controls added in the last two weeks will not be officially measured.
2. Primarily we want to know when our more expensive accessibility support is required. Filtering this support should be doable in this quarter if we can get the primary goal right. Hopefully we can do this goal early.
3. This goal is really about core accessibility work that Alexander is hot to work on. We can create a meta bug for this work. Scoping this goal is tricky.
