Discussed during the group's teleconference on 22nd August 2012:
http://www.w3.org/2012/08/22-audio-minutes#item03

The group discussed the desired behaviour in the following scenario:

1) an AudioParam automation curve is set (via e.g linearRampToValueAtTime() or exponentialRampToValueAtTime()) 
2) during the course of the automation curve, the value is set via AudioParam.value

The question was whether 
1) the setting of that value should be ignored, or
2) the setting should be equivalent to cancelScheduledValues() (cancelling the automation curve) and setting the value

We resolved towards option 2.
