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