            be interspersed by the output generated by the second generator. On each
            iteration it will pass the next consecutive element from the container
            attribute to the first embedded generator. The second embedded generator
            does not get passed any attributes (it gets invoked using an <code class="computeroutput"><span class="identifier">unused_type</span></code> as its attribute). Therefore
