<description summary="control data devices">
This protocol allows a privileged client to control data devices. In
particular, the client will be able to manage the current selection and take
the role of a clipboard manager.
Warning! The protocol described in this file is currently in the testing
phase. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes can
only be done by creating a new major version of the extension.
