<!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
1) The <head> information in this page is significant, should be uniform
across api docs and should be edited only with knowledge of the
templating mechanism.
3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
browser, it will be re-generated from the template, json schema and
authored overview content.
4) The <body>.innerHTML is also generated by an offline step so that this
page may easily be indexed by search engines.
