    // Cache implementations are allowed to modify the markup, to support
    // replacing markup with edge-side include commands. The supporting cache
    // backend will store the markup in some other key (like
    // $data['#real-value']) and return an include command instead. When the
    // ESI command is executed by the content accelerator, the real value can
    // be retrieved and used.
