Subject: [Sipping] draft-ietf-sipping-media-policy-dataset: Specifying bandwidth limitations

Looking at the XML of draft-ietf-sipping-media-policy-dataset, I see this paragraph:

<!--
      <t>If a b= line is present for a media stream, this line MUST be
      used to create the bandwidth elements.</t>
-->

SDP provides "b=" lines for specifying bandwidth limitations.  Similarly, MPD provides <max-bw>, <max-session-bw>, and <max-stream-bw> elements, and the draft states that they are equivalent to various forms of the b= line.  Should we require that when SDP is translated into MPD that the bandwidth limitations be translated?
