The following are the assumed defaults. When they are not defined, the theme will automatically take these values. Default values are defined in _system_rebuild_theme_data().

Note: These defaults apply as a group. In other words, overriding a region with 

regions[sub_header] = Sub-header

will omit the rest of the default regions. To gain them back, they must be redefined. This also applies to stylesheets. Even though it's not technically in a group, defining another stylesheet will prevent "style.css" from being included unless it is redefined.

Stylesheets and JavaScript defaults The style.css and script.js files are only defaults in Drupal 6. In Drupal 7 you must define all CSS and JavaScript files you want the theme to use.
