The Default Home Page uses the OneColumnPage template. This template has two sections: HeaderContent and MainContent. These sections function very similarly to their counterparts in the TwoColumnPage template in that the HeaderContent section resides near the top of the page and extends across the entire page width while the MainContent section appears below the HeaderContent section and extends across the entire page. Most importantly, these sections accept the same cartridge types, and therefore, set up the same cartridge containment strategy for pages that use the OneColumnTemplate.

The XML for the OneColumnPage is located in <ATG11dir>/CommerceReferenceStore/Store/Storefront/deploy/cartridge_templates/OneColumnPage/template.xml and it defines the content type of the OneColumnPage as Page.
