               PartIntro contains introductory text, often an overview
               of the content of the Part.
               
            
Formatted as a displayed block. Sometimes suppressed.
PartIntro content is often printed on a part
                  separator page.

                        Generally, an explicit Label attribute is
                        used only if the processing system is incapable of generating the label
                        automatically. If present, the Label 
                        is normative; it will used even
                        if the processing system is capable of automatic labelling.
