<tp:docstring>
The "primary" interface implemented by an object attached
to a connection. For example, a Gabble plugin implementing
fine-grained control of XEP-0016 privacy lists might expose an object
implementing <tt>com.example.PrivacyLists</tt>.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml">
<p>Request an object with a particular interface providing additional
connection-specific functionality, together with its immutable
properties. These will often be implemented by plug-ins to the
connection managers; for example, support for an XMPP XEP for which
no generic Telepathy interface exists might be implemented by a
Gabble plugin exposing a sidecar with a particular interface.</p>
<p>This method may be called at any point during the lifetime of a
connection, even before its <tp:type>Connection_Status</tp:type>
changes to Connected. It MAY take a long time to
return—perhaps it needs to wait for a connection to be established
and for all the services supported by the server to be discovered
before determining whether necessary server-side support is
available—so callers SHOULD override the default method timeout (25
seconds) with a much higher value (perhaps even MAX_INT32, meaning
“no timeout” in recent versions of libdbus).</p>
<tp:rationale>
<p>There is an implicit assumption that any connection
manager plugin will only want to export one “primary” object per
feature it implements, since there is a one-to-one mapping between
interface and object. This is reasonable since Sidecars are
(intended to be) analogous to extra interfaces on the connection,
providing once-per-connection shared functionality; it also makes
client code straightforward (look up the interface you care about
in a dictionary, build a proxy object from the value). More
“plural” plugins are likely to want to implement new types of
<tp:dbus-ref
namespace="org.freedesktop.Telepathy">Channel</tp:dbus-ref>
instead.</p>
</tp:rationale>
</tp:docstring>
<tp:error name="org.freedesktop.Telepathy.Error.NotImplemented">
<tp:docstring>
The requested sidecar is not implemented by this connection manager,
or a necessary server-side component does not exist. (FIXME: split
these two errors out? Then again, once we list the guaranteed and
possible sidecars on a Protocol object, clients can tell the
difference themselves, because they shouldn't be calling this in the
first case.)
</tp:docstring>

<tp:error name="org.freedesktop.Telepathy.Error.ServiceBusy">
<tp:docstring>
A server-side component needed by the requested sidecar reported it
is currently too busy, or did not respond for some
implementation-defined time. The caller may wish to try again later.

<tp:error name="org.freedesktop.Telepathy.Error.Cancelled">
