+ <p>An interface for connections where it is possible to know what channel
+ types may be requested before the request is made to the connection object.
+ Each capability represents a commitment by the connection manager that it
+ will ordinarily be able to create a channel when given a request with the
+ given type and handle.</p>
+
+ <p>Capabilities can pertain to a certain contact handle, representing
+ activities such as having a text chat or a voice call with the user, or can
+ be on the connection itself (where the handle will be zero), where they
+ represent the ability to create channels for chat rooms or activities such
+ as searching and room listing. The activities are represented by the D-Bus
+ interface name of the channel type for that activity.</p>
+
+ <p>The generic capability flags are defined by ConnectionCapabilityFlag.</p>
+
+ <p>In addition, channel types may have type specific capability flags of their
+ own, which are described in the documentation for each channel type.</p>
+
+ <p>This interface also provides for user interfaces notifying the connection
+ manager of what capabilities to advertise for the user. This is done by
+ using the AdvertiseCapabilities method, and deals with the interface names
+ of channel types and the type specific flags pertaining to them which are
+ implemented by available client processes.</p>
