SVG2 Accessibility API Mappings

Rich,

The document looks good.  I have couple of questions/suggestions.
Ellipse should be treated similar to a circle :)
Should iFrame be treated similarly to a view or possibly like a canvas?
I don't understand why a SVG title element does not get a Default Platform
WAI-ARIA role mapping or a platform WAI-Role role mapping?
