It is regrettable that the 2004 Working Draft of CSS Speech Module Level 3 had to stagnate in transient state for such a long time. At last, new resources means that we were/are able to fix the previous drafts shortcomings, and I am delighted to hear that Apple might be able to participate with reference implementations during the CR stage. :)

The 'speak' property (as defined in the previous WD) is implemented and testable in the public release of iOS 5. I'll file an issue to implement the new values for 'speak' and 'speak-as'

I must've missed the double vertical bars when I read this the first time. This does meet the requirements. Thanks.
