_isValidProperty - shows its private

comment explaining its separate and not to be used

+};

[aazzam, 2016/11/28 23:29:00]

Move to be static methocs on CSSPropertyDescriptor

CSSPropertyDescriptor::get(WidthValue)

+CSSPropertyDescriptor getInvalidDescriptor();

[aazzam, 2016/11/28 23:29:00]

Move to static method in cpp file

OR ideally

Anonymous namespace
namespace blink{
namespace {

void foo() { ..}

}

f;rijeglierjgire
foo()
}

+void add(CSSPropertyDescriptor, CSSPropertyID);

[aazzam, 2016/11/28 23:29:00]

Move to static
CSSPropertyDescriptor::add()

+
+template <class T>
+CSSPropertyDescriptor getDescriptor() {
+  CSSPropertyDescriptor a;
+  a.parseSingleValue = &T::parseSingleValue;

[aazzam, 2016/11/28 23:29:00]

Add ASSERT(a.parse != CSSPropertyAPI::parse)

+  a.getID = &T::getID;
+  a.isValidProperty = true;
+  return a;
+}
+}
