<p>This interface allows many attributes of many contacts to be
obtained in a single D-Bus round trip.</p>
<p>Each contact attribute has an string identifier
(<tp:type>Contact_Attribute</tp:type>), which is namespaced
by the D-Bus interface which defines it.</p>
<p>An initial set of contact attributes is defined here:</p>
<dl>
<dt>org.freedesktop.Telepathy.Connection/contact-id
(type s)</dt>
<dd>The same string that would be returned by
<tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection">InspectHandles</tp:dbus-ref>

</dd>
<dt>org.freedesktop.Telepathy.Connection.Interface.Aliasing/alias

<dd>The same string that would be returned by <tp:dbus-ref
namespace="org.freedesktop.Telepathy.Connection.Interface.Aliasing">GetAliases</tp:dbus-ref>

same as Connection/contact-id, if information from the
Aliasing interface was requested)

<dd>The same string that would be returned by <tp:dbus-ref

(omitted from the result if the contact's avatar token is not known,
present as an empty string if the contact is known not to have
an avatar). Unlike in the <tp:dbus-ref
namespace="org.freedesktop.Telepathy.Connection.Interface.Avatars">GetKnownAvatarTokens</tp:dbus-ref>
method, the avatar tokens for the self handle aren't required to be
present. This attribute should not be used to determine whether or
not the Avatar needs to be set.

contact is known to have no capabilities at all.</dd>

<p>A list of strings indicating which D-Bus interfaces the calling

activity, will be in the reply.</p>
<p>It is an error to request interfaces that are not supported by
this Connection (i.e. mentioned in the
<tp:member-ref>ContactAttributeInterfaces</tp:member-ref>
property).</p>
<tp:rationale>
<p>This makes it possible to distinguish between interfaces for
which the Connection has nothing to say (e.g. we don't know the
avatar tokens of any of the contacts, so we omitted them all),
and interfaces for which this API isn't supported.</p>

<p>Attributes from the interface

<p>As well as returning cached information immediately, the
connection MAY start asynchronous requests to obtain better
values for the contact attributes. If better values are later
obtained by this process, they will be indicated with the usual
signals (such as <tp:dbus-ref
namespace="org.freedesktop.Telepathy.Connection.Interface.Aliasing">AliasesChanged</tp:dbus-ref>).</p>
