-          Once streams have been requested for a channel to this handle (either
-          by calling <tp:member-ref>RequestStreams</tp:member-ref> on a channel
-          with no streams, or by specifying
-          <tp:member-ref>InitialAudio</tp:member-ref> = <tt>True</tt> or
-          <tp:member-ref>InitialVideo</tp:member-ref> = <tt>True</tt>
-          in the channel request), then they cannot be changed;
-          subsequent calls to <tp:member-ref>RequestStreams</tp:member-ref> or
-          <tp:member-ref>RemoveStreams</tp:member-ref> will fail.
-
-          <tp:rationale>
-            For example, once an audio-only Google Talk call has started, it is
-            not possible to add a video stream; both audio and video must be
-            requested at the start of the call if video is desired. User
-            interfaces may use this pseudo-capability as a hint to display
-            separate "Audio call" and "Video call" buttons, rather than a
-            single "Call" button with the option to add and remove video once
-            the call has started for contacts without this flag.
-          </tp:rationale>
+          Channels whose target handle is this contact will have
+          <tp:member-ref>ImmutableStreams</tp:member-ref> = <tt>True</tt>.
