• 'default' => default value,
• 'translatable' => (optional) TRUE/FALSE (wrap in t() on export if true),
• 'contains' => (optional) array of items this contains, with its own defaults, etc. If contains is set, the default will be ignored and assumed to be array().
• 'bool' => (optional) TRUE/FALSE Is the value a boolean value. This will change the export format to TRUE/FALSE instead of 1/0.
