This can be rebased now? :)

If not make it METHOD_IMPLENTED_FOR_PROPERTY
or even API_METHOD_IMPLEMENTED_FOR_PROPERTY
or IS_API_METHOD_...

Ask darren for his opinion ;)

this is gone with the new patch of changing the descriptor, since now the check
for implementation is just
if (cssPropertyDesc.parseSingleValue) // i.e. check if not nullptr

+  descriptor.function != CSSPropertyAPI::function
+
 // Stores function pointers matching those declared in CSSPropertyAPI.
 struct CSSPropertyDescriptor {
   const CSSValue* (*parseSingleValue)(CSSParserTokenRange&,
                                       const CSSParserContext*);
-
-  // Stores whether or not this descriptor is for a valid property. Do not
-  // access the contents of this descriptor unless this value is true.
-  // TODO(aazzam): Remove this once the switch in
-  // CSSPropertyParser::parseSingleValue() has been completely replaced by
-  // CSSPropertyDescriptors.
-  bool temporaryCanReadValue;
+  bool (*parseShorthand)(bool, CSSParserTokenRange&, const CSSParserContext*);
 
   // Returns the corresponding CSSPropertyDescriptor for a given CSSPropertyID.
   // Use this function to access the API for a property. Returns a descriptor
