inside dictionary:

<http://internaut.com:8080/%7Ebaboba/ortc/ortc-4-24-2014-revised.html#widl-RTCRtpCapabilities-headerExtensions>;
   sequence<DOMString> features 
<http://internaut.com:8080/%7Ebaboba/ortc/ortc-4-24-2014-revised.html#widl-RTCRtpCapabilities-features>;
};


The definition should mention the IANA registry for RTP header 
extensions URIs so it's clear where those definitions come from...
