[css3-speech] voice-stress, missing default value

The 'voice-stress' property defined in the CSS3 Speech module is  
pretty much a direct adaptation of SSML's 'emphasis' element [1].

There is however an significant oversight: the 'voice-stress' property  
needs a value so that authors can indicate that the emphasis should be  
the default one produced by the speech synthesizer. This is language- 
dependent, and not related to document markup, so it is not something  
that can be defined in the user-agent stylesheet (TTS-generated  
emphasis typically applies to arbitrary words within sentences).

I added the 'auto' value in the latest editors' draft [2], along with  
an example to clarify the use of 'voice-stress'. Please kindly review.  
If 'auto' is not a suitable value name, maybe 'default' or 'normal' ?

Regards, Daniel
