A new use for the Documentary Hypothesis

Biblical scholars have long been familiar with the Documentary Hypothesis of Karl Heinrich Graf and Julius Wellhausen, which uses literary analysis to determine authorship of the books of the Pentateuch. Now it seems that contemporary scholars are finding that this theory has wider applications: "New Directions in Pooh Studies: ueberlieferungs- und religionsgeschichtliche Studien zum Pu-Buch." I am sure Rich Greydanus will appreciate this.
