This isn't the case. Vendor prefixes have several different purposes  
including, highlighting partial inplementations of W3C specs, as well  
as being used when vendors decide to include proprietary or  
experimental  feature inplementations.

Some time ago in this list, there was a call for suggestions as to  
what features the new validator should include. I for one suggested  
that the new validator should recognise each prefix and inform the  
user that they are using a property that will be recognised only by a  
specific browser.

I suggest that this method is a better solution than for the validator  
to just ignore properties prepended with these extensions.
