What you should do is define a serializer.  See and I suspect what you 
want here is:

   serializer = { attribute };

for interfaces that don't inherit from something that needs 
serialization but want to serialize all their own attributes or

   serializer = { inherit, attribute };

for ones that want to serialize their own attributes plus whatever their 
parent interface serializes.  This will automatically create a toJSON 
method that does the right things for you.

I suggest you test what UAs do and whether the spec you write is 
compatible with that.

Gecko does have a serializer on PerformanceEntry and on 
PerformanceTiming, for what that's worth.
