+ * SVGPathElement.createSVGPathSegXxx().

+ *
+ * See the architecture comment in DOMSVGLength.h (yes, LENGTH) for an overview
+ * of the important points regarding how this specific class works.
+ *
+ * The main differences between this class and DOMSVGLength is that we have
+ * sub-classes (it does not), and the "internal counterpart" that we provide a
+ * DOM wrapper for is a list of floats, not an instance of an internal class.
