Note: | |
2 1) The <head> information in this page is significant, should be uniform | |

5 3) All <body>.innerHTML is genereated as an rendering step. If viewed in a | |
6 browser, it will be re-generated from the template, json schema and | |
7 authored overview content. | |
8 4) The <body>.innerHTML is also generated by an offline step so that this | |
