-      <p>An interface for multi-user conference channels that can "continue
-        from" one or more individual channels. This could be used to invite
-        other contacts to an existing 1-1 text conversation, combine two phone
-        calls into one conference call, and so on, with roughly the same API in
-        each case.</p>
-
-      <tp:rationale>
-        <p>This interface addresses freedesktop.org <a
-            href="http://bugs.freedesktop.org/show_bug.cgi?id=24906">bug
-            #24906</a> (GSM-compatible conference calls) and <a
-            href="http://bugs.freedesktop.org/show_bug.cgi?id=24939">bug
-            #24939</a> (upgrading calls and chats to multi-user).
-          See those bugs for more rationale and use cases.</p>
-      </tp:rationale>
-
-      <p>Existing channels are upgraded by requesting a new channel of the same
-        <tp:dbus-ref
-        namespace="org.freedesktop.Telepathy.Channel">ChannelType</tp:dbus-ref>,
-        listing the channels to be merged into the new conference in the
-        <tp:member-ref>InitialChannels</tp:member-ref> property of the request.
-        If <tp:member-ref>InitialInviteeHandles</tp:member-ref> and
-        <tp:member-ref>InitialInviteeIDs</tp:member-ref> are
-        <var>Allowed_Properties</var> in <tp:dbus-ref
-          namespace="org.freedesktop.Telepathy.Connection.Interface.Requests">RequestableChannelClasses</tp:dbus-ref>,
-        ad-hoc conferences to a set of contacts may be created by requesting a
-        channel, specifying
-        <tp:member-ref>InitialInviteeHandles</tp:member-ref> and/or
-        <tp:member-ref>InitialInviteeIDs</tp:member-ref> to be the contacts in
-        question. A request may specify these alongside
-        <tp:member-ref>InitialChannels</tp:member-ref>, to simultaneously
-        upgrade a channel to a conference and invite others to join it.</p>
-
-      <p>Channels with this interface MAY also implement <tp:dbus-ref
-        namespace='ofdT.Channel.Interface'>MergeableConference.DRAFT</tp:dbus-ref>
-        to support merging more 1-1 channels into an ongoing conference.
-        Similarly, 1-1 channels MAY implement <tp:dbus-ref
-        namespace='ofdT.Channel.Interface'>Splittable.DRAFT</tp:dbus-ref> to
-        support being broken out of a Conference channel.</p>
-
-      <p>The <tp:dbus-ref
-          namespace="org.freedesktop.Telepathy.Channel.Interface"
-          >Group</tp:dbus-ref> interface on Conference channels MAY use
-          channel-specific handles for participants; clients SHOULD support
-          both Conferences that have channel-specific handles, and those that
-          do not.</p>
-
-      <tp:rationale>
-        <p>In the GSM case, the Conference's Group interface MAY have
-          channel-specific handles, to represent the fact that the same
-          phone number may be in a conference twice (for instance, it could be
-          the number of a corporate switchboard).</p>
-
-        <p>In the XMPP case, the Conference's Group interface SHOULD have
-          channel-specific handles, to reflect the fact that the participants
-          have MUC-specific identities, and the user might also be able to see
-          their global identities, or not.</p>
-
-        <p>In most other cases, including MSN and link-local XMPP, the
-          Conference's Group interface SHOULD NOT have channel-specific
-          handles, since users' identities are always visible.</p>
-      </tp:rationale>
-
-      <p>Connection managers implementing channels with this interface
-        MUST NOT allow the object paths of channels that could be merged
-        into a Conference to be re-used, unless the channel re-using the
-        object path is equivalent to the channel that previously used it.</p>
-
-      <tp:rationale>
-        <p>If you upgrade some channels into a conference, and then close
-          the original channels, <tp:member-ref>InitialChannels</tp:member-ref>
-          (which is immutable) will contain paths to channels which no longer
-          exist. This implies that you should not re-use channel object paths,
-          unless future incarnations of the path are equivalent.</p>
-
-        <p>For instance, on protocols where you can only have
-          zero or one 1-1 text channels with Emily at one time, it would
-          be OK to re-use the same object path for every 1-1 text channel
-          with Emily; but on protocols where this is not true, it would
-          be misleading.</p>
-      </tp:rationale>
-
-      <h4>Examples of usage</h4>
-
-      <p>A pair of 1-1 GSM calls <var>C1</var> and <var>C2</var> can be merged
-        into a single conference call by calling:</p>
-
-      <blockquote>
-        <code><tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection.Interface.Requests">CreateChannel</tp:dbus-ref>({
-            ...<tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">ChannelType</tp:dbus-ref>: ...Call,
-            ...<tp:member-ref>InitialChannels</tp:member-ref>: [C1, C2]
-          })</code>
-      </blockquote>
-
-      <p>which returns a new channel <var>Cn</var> implementing the conference
-        interface. (As a quirk of GSM, both 1-1 will cease to function normally
-        until they are <tp:dbus-ref
-          namespace="ofdT.Channel.Interface.Splittable.DRAFT">Split</tp:dbus-ref>
-        from the conference, or the conference ends.)</p>
-
-      <p>An XMPP 1-1 conversation <var>C3</var> (with
-        <tt>chris@example.com</tt>, say) can be continued in a newly created
-        multi-user chatroom by calling:</p>
-
-      <blockquote>
-        <code>CreateChannel({
-            ...ChannelType: ...Text,
-            ...<tp:member-ref>InitialChannels</tp:member-ref>: [C3]
-          })</code>
-      </blockquote>
-
-      <p>Or, to invite <tt>emily@example.net</tt> to join the newly-created MUC
-        at the same time:</p>
-
-      <blockquote>
-        <code>CreateChannel({
-            ...ChannelType: ...Text,
-            ...<tp:member-ref>InitialChannels</tp:member-ref>: [C3],
-            ...<tp:member-ref>InitialInviteeIDs</tp:member-ref>: ['emily@example.net']
-          })</code>
-      </blockquote>
-
-      <p>To continue <var>C3</var> in a particular multi-user
-        chatroom (rather than the implementation inventing a unique name for
-        the room), call:</p>
-
-      <blockquote>
-        <code><tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection.Interface.Requests">EnsureChannel</tp:dbus-ref>({
-            ...ChannelType: ...Text,
-            ...<tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">TargetHandleType</tp:dbus-ref>: ...Room,
-            ...<tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">TargetID</tp:dbus-ref>: 'telepathy@conf.example.com',
-            ...<tp:member-ref>InitialChannels</tp:member-ref>: [C3]
-          })</code>
-      </blockquote>
-
-      <p>Note the use of EnsureChannel — if a channel for
-        <tt>telepathy@conf.example.com</tt> is already open, this SHOULD be
-        equivalent to inviting <tt>chris@example.com</tt> to the existing
-        channel.</p>
-
-      <p>In the above cases, the text channel <var>C3</var> SHOULD remain open
-        and fully functional (until explicitly closed by a client); new
-        incoming 1-1 messages from <tt>chris@example.com</tt> SHOULD appear in
-        <var>C3</var>, and messages sent using <var>C3</var> MUST be relayed
-        only to <tt>chris@example.com</tt>.</p>
-
-      <tp:rationale>
-        <p>If there is an open 1-1 text channel with a contact, in every
-          other situation new messages will appear in that channel. Given
-          that the old channel remains open — which is the least surprising
-          behaviour, and eases us towards a beautiful world where channels
-          never close themselves — it stands to reason that it should be
-          where new messages from Chris should appear. On MSN, creating a
-          conference from <var>C3</var> should migrate the underlying
-          switchboard from <var>C3</var> to the new channel; this is an
-          implementation detail, and should not affect the representation on
-          D-Bus. With a suitable change of terminology, Skype has the same
-          behaviour.</p>
-
-        <p>If the current handler of that channel doesn't want this to happen
-          (maybe it transformed the existing tab into the group chat window,
-          and so there'd be no UI element still around to show new messages),
-          then it should just <tp:dbus-ref
-          namespace="org.freedesktop.Telepathy.Channel">Close</tp:dbus-ref> the
-          old 1-1 channel; it'll respawn if necessary.</p>
-      </tp:rationale>
-
-      <p>Either of the XMPP cases could work for Call channels, to
-        upgrade from 1-1 Jingle to multi-user Jingle. Any of the XMPP cases
-        could in principle work for link-local XMPP (XEP-0174).</p>
-
-      <p>XMPP and MSN do not natively have a concept of merging two or more
-        channels C1, C2... into one channel, Cn. However, the GSM-style
-        merging API can be supported on XMPP and MSN, as an API short-cut
-        for upgrading C1 into a conference Cn (which invites the
-        TargetHandle of C1 into Cn), then immediately inviting the
-        TargetHandle of C2, the TargetHandle of C3, etc. into Cn as well.</p>

-                             >RequestableChannelClasses</tp:dbus-ref></h4>
-
-      <p>A GSM connection might advertise the following channel class for
-        conference calls:</p>

-          NOT be altered by merging them into a conference. However, depending on
-          the protocol, the Channels MAY be placed in a "frozen" state by placing
-          them in this property's value or by calling
-          <tp:dbus-ref
-            namespace="org.freedesktop.Telepathy.Channel.Interface"
-            >MergeableConference.DRAFT.Merge</tp:dbus-ref> on them.</p>
-
-        <tp:rationale>
-          <p>In Jingle, nothing special will happen to merged calls. UIs MAY
-            automatically place calls on hold before merging them, if that is
-            the desired behaviour; this SHOULD always work. Not doing
-            an implicit hold/unhold seems to preserve least-astonishment.</p>
-
-          <p>In GSM, the calls that are merged go into a state similar to
-            Hold, but they cannot be unheld, only split from the conference
-            call using <tp:dbus-ref namespace="org.freedesktop.Telepathy"
-              >Channel.Interface.Splittable.DRAFT.Split</tp:dbus-ref>.</p>
-        </tp:rationale>
-
-        <p>Depending on the protocol, it might be signalled to remote users
-          that this channel is a continuation of all the requested channels,
-          or that it is only a continuation of the first channel in the
-          list.</p>
-
-        <tp:rationale>
-          <p>In MSN, the conference steals the underlying switchboard (protocol
-            construct) from one of its component channels, so the conference
-            appears to remote users to be a continuation of that channel and no
-            other. The connection manager has to make some arbitrary choice, so
-            we arbitrarily mandate that it SHOULD choose the first channel in
-            the list as the one to continue.</p>

-
-        <tp:rationale>
-          <p>On GSM you have to place a 1-1 call before you can merge it into a

-            Muji calls and XMPP/MSN/Skype ad-hoc chat rooms without starting a

-        </tp:rationale>
-
-        <p>If included in a request, the given contacts are automatically

-          <p>For example, if you have a 1-1 channel C1 with Rob, and you want
-            to invite Sjoerd to join the discussion, you can do so by
-            requesting a channel with InitialChannels=[C1] and
-            InitialInviteeHandles=[sjoerd],

-        </tp:rationale>
-
-        <p>If a request includes some combination of InitialInviteeHandles,
-          InitialInviteeIDs and InitialChannels, then the value of
-          InitialInviteeHandles on the resulting channel SHOULD be the union of
-          the handles from InitialInviteeHandles, the handles corresponding
-          to the InitialInviteeIDs, and the target handles of the
-          InitialChannels, with any duplicate handles removed. Because this

-          <p>This simplifies identification of new channels in clients - they

-            after either of the requests mentioned above, the NewChannels
-            signal would announce the channel with InitialChannels=[C1],
