      <FormatDescription>The documents (files) created by Adobe Illustrator are PostScript language
documents. A PostScript language document description that minimally conforms to the Document Structuring Conventions has two main parts: a prolog and a script. The prolog encapsulates information needed by other programs to interpret the file. The script describes the graphic elements on the page.
Beginning with version 9, the Adobe Illustrated ai file format included both a pdf copy of the illustration and a postscript copy.</FormatDescription>
