Annex C: 

C.1 = Introduction
 This Annex provides the = formal MIME type registration for the MPD. It is referenced from the = registry at http://www.iana.org/.

C.2 MIME type and = subtype
 The MIME Type and Subtype are defined = as follows:
 =E2=8E=AF MIME = media type name: = application
 =E2=8E=AF MIME = subtype name: = dash+xml
 =E2=8E=AF Required = parameters: = none
 =E2=8E=AF Optional = parameters: = The =E2=80=98profiles=E2=80=99 parameter as documented in Annex = C.3.1 in this part of ISO/IEC 23009
 =E2=8E=AF Encoding = considerations: = the same media type encoding considerations specified in section = 3.2 of RFC 3023
 =E2=8E=AF Security = considerations: = The MPD is a Media Presentation Description and contains = references to other resources. It is coded in XML, and there are = risks that deliberately malformed XML could cause security issues. = In addition, an MPD could be authored that causes receiving clients = to access other resources; if widely distributed, this could be = used to cause a denial-of-service = attack.
 =E2=8E=AF Interoperability = considerations: 
The specification defines a = platform-independent expression of a presentation, and it is intended = that wide interoperability can be = achieved.
 =E2=8E=AF Published = specification: = ISO/IEC 23009-1: Information technology =E2=80=94 Dynamic = adaptive streaming over HTTP (DASH) =E2=80=94 Part 1: Dynamic = adaptive streaming over HTTP (DASH)
 =E2=8E=AF = Applications which use this media type:  = various
 =E2=8E=AF = Additional information:
  =E2=8E=AF File = extension(s): = mpd
=  =E2=8E=AF Intended usage: = common
 =E2=8E=AF Other = Information/General Comment: = none
 =E2=8E=AF Person to = contact for further information:
  =E2=8E=AF = Name: = Thomas Stockhammer
  =E2=8E=AF = Email: = stockhammer@nomor.de
<= div>
 =E2=8E=AF Author/Change controller: ISO/IEC = JTC1/SC29 (MPEG)

C.3 = Parameters
 C.3.1 The = profiles parameter
 Parameter name: = profiles
 Parameter value: The = 'profiles' parameter is an optional parameter that indicates one or more = profiles to which the file claims conformance. The contents of this = attribute shall conform to either the pro-simp or pro-fancy productions = of RFC6381, Section 4.5. The profile identifiers reported in the = MIME type parameter should match identically the profiles reported = in the profiles attribute in the MPD itself (see Clause = 8).

 example:
  = application/dash+xml;profiles=3D"urn:mpeg:dash:profiles:mythical,ur= n:3gpp:dash:profiles:fictional"

=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Please provide any = comments asap, latest by December = 6th.
