+/**
+ * This nsISMILType class is a special case for the 'orient' attribute on SVG's
+ * 'marker' element.
+ *
+ *   orient = "auto | auto-start-reverse | <angle>"
+ *
+ * Unusually, this attribute doesn't have just a single corresponding DOM
+ * property, but rather is split into two properties: 'orientType' (of type
+ * SVGAnimatedEnumeration) and 'orientAngle' (of type SVGAnimatedAngle). If
+ * 'orientType.animVal' is SVG_MARKER_ORIENT_ANGLE, then
+ * 'orientAngle.animVal' contains the angle that is being used. The lacuna
+ * value is 0.
+ *
+ * The SVG 2 specification does not define a
+ * SVG_MARKER_ORIENT_AUTO_START_REVERSE constant value for orientType to use;
+ * instead, if the attribute is set to "auto-start-reverse",
+ * SVG_MARKER_ORIENT_UNKNOWN is used.  Internally, however, we do use a
+ * constant with this name.
