!!! Overview 
A [{$pagename}] is a [DirXML Variable] that gets its value from the [Global Configuration Value|2.16.840.1.113719.1.14.4.1.54] (GCV) attribute that is defined for the [DirXML-Driver] or the [driverset]. 

Global [Configuration] [variables] are by definition during run-time read-only and are only read at the startup of a driver. 

A global variable may exist in one of two different scopes: 
* [Driver Scope] - Identified by [DirXML-Driver] scope 
* [Driverset Scope] - Identified by [driverset|2.16.840.1.113719.1.14.6.1.1] scope
