There is a clear use case for creating a profile whereby an author could only
use <canvas> and JavaScript as part of the profile opening the doors for a
whole plethora of applications that run cross platform through the availability
of a common drawing capability. At the 2010 tech plenary a person from the TV
community about HTML profiles and the person stated that a subset of HTML which
contained <canvas> and HTML would "hit the sweet spot."

A number of issues still remain that are not addressed to address this issue.
They are:

- Provide Access to the blink rate of the OS.
- Synchronizing the caret position in a content editable <canvas> subtree to
the screen position rendered on the canvas and convey that information to a
magnifier.
- Convey the persons current selection position when higlighting text to a
screen reader and synchronize that with what is in the contenteditable area in
the subtree for a screen reader.
- Convey the location of grammatical and spelling errors in a contenteditable
canvas subtree to an author so that the author may synchronize them with what
is rendered on the visual canvas.
- Assess what HTML elements in the canvas subtree are allowed in the subtree.
For example, should an IFrame be allowed?
