    abstract =  {This document registers the application/sdpfrag Multipurpose Internet Mail Extensions (MIME) media type. This type is similar to application/sdp, but allows certain subsets of well formed session descriptions, as per the Session Description Protocol (SDP), to be represented instead of requiring a complete SDP session description. The "a=candidate" lines that are incrementally exchanged between Trickle ICE agents are one example usage of the application/sdpfrag.},
