+ <description summary="list and control workspaces">
+ Workspaces, also called virtual desktops, are groups of surfaces. A
+ compositor with a concept of workspaces may only show some such groups of
+ surfaces (those of 'active' workspaces) at a time. 'Activating' a
+ workspace is a request for the compositor to display that workspace's
+ surfaces as normal, whereas the compositor may hide or otherwise
+ de-emphasise surfaces that are associated only with 'inactive' workspaces.
+ Workspaces are grouped by which sets of outputs they correspond to, and
+ may contain surfaces only from those outputs. In this way, it is possible
+ for each output to have its own set of workspaces, or for all outputs (or
+ any other arbitrary grouping) to share workspaces. Compositors may
+ optionally conceptually arrange each group of workspaces in an
+ N-dimensional grid.
+
+ The purpose of this protocol is to enable the creation of taskbars and
+ docks by providing them with a list of workspaces and their properties,
+ and allowing them to activate and deactivate workspaces.
+
+ After a client binds the zcosmic_workspace_manager_v1, each workspace will be
+ sent via the workspace event.

+
+ This allows changes to the workspace properties to be seen as atomic,
