// The most commonly used values for |type| are "svc", "debug", and "ctrl".
// Services published under "svc" are made available to clients via
// |fuchsia.sys.Lancher#CreateComponent|. The "debug" serivices are exposed via

// first argument.
// This may fail in two ways. If an entry with the given
// |service_name| already exists, this returns
// ZX_ERR_ALREADY_EXISTS. If the provided |service_name| is invalid,
// ZX_ERR_INVALID_ARGS is returned. Otherwise, this returns ZX_OK.
