Your QM includes a description of the structure that is not graphical, correct? Just ask the auditor to provide some rational basis for his apparent belief that "outline"="drawing." You may want to show him this, from the American Heritage Dictionary:
[SIZE=-1]NOUN:[/SIZE]1a. A line marking the outer contours or boundaries of an object or figure. b. The shape of an object or figure. 2a. A style of drawing in which objects are delineated in contours without shading. b. A sketch done in this style. 3a. A general description covering the main points of a subject: an outline of American literature. b. A statement summarizing the important points of a text. c. A summary of a written work or speech, usually analyzed in headings and subheadings. 4. A preliminary draft or plan, as of a project or proposal.
