     <enum name="resize">
+      <description summary="resize type enumeration">
+	Used to determine the resize behavior, including the cursor
+	image during resize. There are 8 fixed modes, 4 base and 4
+	combination. These fixed modes can be stored in a 4 bit
+	mask where each bit represents one of the base modes. The
+	combination modes are a sum of their components while values
+	representing conflicting modes are not used. For example,
+	top_left(5) = top(1) + left(4) and top_right(9) = top(1) +
+	right(8) while unused(3) = top(1) + bottom(2) (value unused,
+	conflicting combination). Values above 15 are reserved for
+	additional flags.
