+    # The Transitive formatter writes an XML document that parses to an
+    # identical document as the source document.  This means that no extra
+    # whitespace nodes are inserted, and whitespace within text nodes is
+    # preserved.  Within these constraints, the document is pretty-printed,
+    # with whitespace inserted into the metadata to introduce formatting.
+    #
+    # Note that this is only useful if the original XML is not already
+    # formatted.  Since this formatter does not alter whitespace nodes, the
+    # results of formatting already formatted XML will be odd.
