[whatwg] Exposing spelling/grammar suggestions in contentEditable

[Charles Pritchard]

Regarding:
http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2010-December/029559.html

This has (somewhat) been resolved: Benjamin has pointed out that 
aria-invalid = "spelling|grammar"
would work just fine with <mark>. It's simply not implemented by vendors 
at the moment. It is covered
by the WAI ARIA 1.0 LC doc.
