Note that this is for element attributes, not interface members. Having  
said that, vendor-name (i.e. a single dash) is probably sufficient. It  
seems highly unlikely we will ever use webkit-, ms-, o-, gecko- as an  
attribute name. In fact, iirc we follow the policy that new attribute  
names will not have hyphens in them, unless it is for some kind of pattern  
(like data-).
