+ * The Presentation Text object is the data object used in document processing
+ * environments for representing text which has been prepared for presentation.
+ * Text, as used here, means an ordered string of characters, such as graphic
+ * symbols, numbers, and letters, that are suitable for the specific purpose of
+ * representing coherent information. Text which has been prepared for
+ * presentation has been reduced to a primitive form through explicit
+ * specification of the characters and their placement in the presentation
+ * space. Control sequences which designate specific control functions may be
+ * embedded within the text. These functions extend the primitive form by
+ * applying specific characteristics to the text when it is presented. The
+ * collection of the graphic characters and control codes is called Presentation
+ * Text, and the object that contains the Presentation Text is called the
+ * PresentationText object.
