      The draw:concave attribute specifies whether a regular polygon is convex or concave. For a convex regular polygon, the polygon corners are located on a single circle which has its center in the center of the polygon. In a concave regular polygon, two such circles are required, and corners that are located next to each other are located on different circles. Specifying a concave regular polygon requires the use of the draw:sharpness attribute in addition to the draw:concave attribute.
      Note: An example of a convex regular polygon is a hexagon. An example of a concave regular polygon is a star.

      Section 17.127 draw:concave

      Ed. Note While the explanation is correct for one class of concave polygons it is not correct for all. A polygon with one interior angle greater than 180 degrees is also a concave polygon. The draw:shapness attribute only enables the drawing of only one type of concave polygon. That's ok, but we need to say it is a limited class of polygons to which this applies.
