The validator aims to look for specification compliance, at least this is
what it should do. Though proprietary extensions are generally allowed [1],
they are not part of the specification, so the validator would then only
check for correct syntax.

Also, how would you decide what proprietary properties to be added? Only
Gecko supported properties using the "-moz-" prefix? Gecko and Microsoft
properties? Others as well? Where to get the information on changes and
additions?
