 (draft 1) This object represents one Content inside a Call. For example in an audio/video call there would be one audio and one video content. Each content has one or more Stream.DRAFT objects which represent the actual transport to one or more contacts. Remove the content from the call. Raised when a Call doesn't support removing contents (e.g. a Google Talk video call)

Extra interfaces provided by this content, such as Content.Interface.Media.DRAFT or Content.Interface.Mute.DRAFT. This SHOULD NOT include the Content interface itself, and cannot change once the content has been created.

The name of the content. [FIXME: rationale?]

The media type of this content

The creator of this content

 [FIXME] The content has no specific disposition [FIXME: what does this mean?]

The content was initially part of the call. When Accept is called on the channel, all streams of this content where the self-handle's sending state in Senders is Sending_State_Pending_Send will be moved to Sending_State_Sending as if SetSending(TRUE) had been called.

 The disposition of this content. This property cannot change.

Emitted when a stream is added to a call

 The stream which was added

Emitted when a stream is added to a call

 The stream which was removed

The list of Stream.DRAFT objects that exist in this content.

In a conference call multiple parties can share one media content (say, audio), but the streaming of that media can either be shared or separate. For example, in a multicast conference all contacts would share one stream, while in a Muji conference there would be a stream for each participant.

Change notification is via StreamAdded and StreamRemoved.
