-
-        The <configSections> section controls the registration of sections.
-        Section is the basic unit of deployment, locking, searching and
-        containment for configuration settings.
-        
-        Every section belongs to one section group.
-        A section group is a container of logically-related sections.
-        
-        Sections cannot be nested.
-        Section groups may be nested.
-        
-        <section
-            name=""  [Required, Collection Key] [XML name of the section]
-            allowDefinition="Everywhere" [MachineOnly|MachineToApplication|AppHostOnly|Everywhere] [Level where it can be set]
-            overrideModeDefault="Allow"  [Allow|Deny] [Default delegation mode]
-            allowLocation="true"  [true|false] [Allowed in location tags]
-        />
-        
-        The recommended way to unlock sections is by using a location tag:
-        <location path="Default Web Site" overrideMode="Allow">
-            <system.webServer>
