When you open an existing Evaluation Specification or create a new one, you will see the Evaluation Specification Document Tree View on the left side of the window, and a Details View on the right side.

The following screen shot shows the Editor window as it appears when you open the demo Evaluation Specification.

The Evaluation Specification Document Tree View allows you to navigate the tree structure. Whenever you select a tree node, the Details View changes in order to allow you to fill in node-specific information.
