Missing variable in template documentation

Hello,

Can you please help me, what is the variable to generate this part of the code:

          var canvas, stage, exportRoot, anim_container, dom_overlay_container, fnStartAnimation;

function init() {

canvas = document.getElementById("canvas");

anim_container = document.getElementById("animation_container");

dom_overlay_container = document.getElementById("dom_overlay_container");

Because $CREATE_LOADER variable doesnt create this few lines, it creates only 2 lines, which is the following:

var comp=AdobeAn.getComposition("88A0284D8D8DB446AC4E51582F1F3DAA");

var lib=comp.getLibrary();

Thank you in advance!

Peter
