        <pre>We need the serializer operation support for the WebIDL in order to implement the WebRTC API:

<a href="https://github.com/w3c/webrtc-pc/issues/204">https://github.com/w3c/webrtc-pc/issues/204</a>

We are going to add just the required support for our goals but not the complete serializer support, it will include support for:
   - just the keyword: serializer; It will return all the attributes of in an object.
   - map of entries with the attributes: serializer = {attribute1, attribute2, ...}
   - list of attributes: serializer = [attribute1, attribute2, ...]
   - DOMString and unsigned shor types

It creates a toJSON method that returns the serialized value converted into an ECMAScript value. For more information check the definition of the operation:

<a href="http://heycam.github.io/webidl/#idl-serializers">http://heycam.github.io/webidl/#idl-serializers</a>

We are modifying already RTCSessionDescription and RTCIceCandidate idls to use the operation, that way we can remove the polyfill we were using in the examples for WebKit.</pre>
