<description summary="A better way to use the computer">
Most programs operate on data with a known location. This protocol
provides the base for a windowing system centered around URIs.
Individual windows are not provided by single apps. Instead they
are made up of a scheme handler, which uses a URI to retrieve some
data, and an ad-hoc series of renderers which produces the final
wl_surface to be rendered.
This protocol only defines the interface for scheme handlers and
renderers to connect and facilitate the rendering of windows. The
mechanism by which such clients are started, routed, or otherwise
configured is out-of-scope for this protocol. Similarly, client
enumeration, surface enumeration, and other forms of generic IPC
are out-of-scope.
This document is currently unstable, and should be used with the
assumption of breaking protocol changes without version bumps.
