Meaning of # in variables

I was looking at some module code:

$element['location_settings'] = array( '#type' => 'value', '#value' => $element['#location_settings'], );

What is the meaning of # in #location_settings And i'm unsure whether $element['#location_settings'] is a form element or just a regular variable in this case.

'#' is for Drupal theming, Drupal will read those variables for theming hook. These variable are not general, it means nothing if not passed into form function or theming function.

In the Drupal FAPI all variables (keys), that starts with '#' treated as properties/data of the current node, all other variables treated as children nodes. This is just a FAPI convention.

So, $element['#location_settings'] can't be children form element, only regular variable.
