1) Core 1.0 #14: "WICD user agents must make all visible and focusable
points in the XHTML layer and the positioned Overlay Object reachable
and activatable."
http://bugs.webkit.org/show_bug.cgi?id=16483"AFAICT the clicks should always hit the <object> element. Until this
is specified otherwise, I think this should be closed as invalid."
2) Mobile 1.0 #18-1: Support for SVG 1.2 editable="simple" attribute
on <text>
http://bugs.webkit.org/show_bug.cgi?id=16275"Editing is mapped into style (-webkit-user-modify), so you can map
this SVG editable attribute into that and get editing behavior."
