-// A surface ID is composed of two parts, a local part and a namespace. The
-// local part is allocated by the client using any scheme that avoids
-// duplicates. The namespace is allocated by the service and will be different
-// for each client (aka each connection to mojo.Surface).
-//
-// The special id_namespace value 0 is equivalent to the namespace of the
-// client. This can be used to create, destroy and submit frames to
-// surfaces before learning the namespace and to reference other surfaces
-// owned by the same client. The actual id namespace must be used to pass
-// surface ids to other clients for them to reference.
