Outline Instances Tab (PDF Documents)
The Outline Instance tab is used for Instance elements and
place holders for Metadata, Prolog, and Body. This view has the same feel as working in
the Outline Editor, with a slight change to accommodate the
place holders. This perspective provides an experience where the requirements file is
presented in an outline based on the XML structure of the file. 
In this view, you will be able to go through the different changes that apply to the document. To understand the process of applying changes, refer to Accepting and Rejecting Changes.
This window allows you to browse through the document's hierarchy,
expand and collapse nodes, as well as look at the PTR logic. The PTR Editor is read
only.
