[Standards] XEP-0167: Jingle RTP Sessions - payload type parameters w/o value?

Hi,

I've seen a couple of Jingle RTP implementations in the wild that send
XML looking like this: (note the lack o a 'name' attribute)

<payload-type channels="1" name="telephone-event" clockrate="8000" id="101">
  <parameter value="0-15" xmlns="urn:xmpp:jingle:apps:rtp:1"/>
</payload-type>

which is illegal according to the (non normative) scheme (both name
and value are required attributes) whereas the normative text doesn’t
say anything on whether either or both value and name can be omitted.

Can someone more familiar with what this actually maps to clarify?

Note that the implementations sending this are parsing this from firefoxes SDP.

cheers
Daniel
