This is largely ripped from somebar's ipc patchset; just with some personal modifications.
I would probably just submit raphi's patchset but I don't think that would be polite.

<protocol name="dwl_ipc_unstable_v2">
<description summary="inter-proccess-communication about dwl's state">
This protocol allows clients to update and get updates from dwl.
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 number is
reset.

<description summary="manage dwl state">
This interface is exposed as a global in wl_registry.
Clients can use this interface to get a dwl_ipc_output.

The dwl_ipc_manager.tags and dwl_ipc_manager.layout events expose tags and layouts to the client.
