 it means that [V8EnabledAtRuntime] is specified on all the attributes and methods of the interface,
 
+== [V8EnabledPerContext](i,m,a) == #V8EnabledAtRuntime
+
+Summary: In Chromium/V8, you can enable or disable a flag per execution context (that is DOMWindow).
+
+If you specify [V8EnabledPerContext], you need to write "flag-binding" code
+in WebCore/bindings/generic/ContextEnabledFeatures.h, WebCore/bindings/generic/ContextEnabledFeatures.cpp
+The implementation can choose arbitrary decision logic. A typical approach is to ask FrameLoaderClient about its availability.
+
+Currently, V8EnabledPerContext is only effective for attributes on DOMWindow.
