Classpath Tab
The Classpath tab displays a list of folders and JAR libraries that hold implementations for API extensions, implementations for custom Author mode operations, various resources (such as stylesheets), and framework translation files. Oxygen XML Author loads the resources looking in the folders in the order they appear in the list (from top to bottom).
