Here's a list of all the things that go into the pagetable.
Default values put there by the CMS code at the beginning of the rendering process.
All the # directives in a super-global object that I created (this is where the built-in templates come from).
All the # directives in your global preference outline called cmsPrefs.opml.
All the attributes from all the headlines on the path to the headline being rendered.
All the # directives on the path to the headline being rendered.
The order above is important because values in the pagetable can be overridden. So if you want to change a default that's the global object, just put a different value for it in your cmsPrefs.opml file.
