  <interface name="zdwl_ipc_manager_v2" version="2">
    <description summary="manage dwl state">
      This interface is exposed as a global in the Wayland registry and allows
      clients to query and set dwl state.

      Warning! The protocol described in this file is experimental and
      backward incompatible changes may be made. Backward compatible changes
      may be added together with the corresponding interface version bump.
      Backward incompatible changes are done by bumping the version number in
      the protocol and interface names and resetting the interface version.
      Once the protocol is to be declared stable, the 'z' prefix and the
      version number in the protocol and interface names are removed and the
      interface version is reset.
