That said, you can create a custom field with text content to display IF it exists in or outside of the loop.
For example, using c2c's excellent get custom plugin, you can add a custom field to the desired page (let's call the key "default-text") and call that from your custom page template outside of the loop with the plugin's c2c_get_recent_custom('default-text'); function. But of course, that means the text will display for every page that uses your custom template, which is great if you have a common element for all pages.
Within the loop however, you can call SPECIFIC text (default-text) for the current page only IF the custom field 'default-text' exists for that page using c2c_get_custom('default-text');
It will only display the specific text WHEN and IF that field exists for THAT page.

It's the one of my MUST-USE plugins for every site done as a CMS
