It already says this, yes?

This also matches up with the normalizedPathSegList from SVG 1.0

> Provides access to the base (i.e., static) contents of the ‘d’ attribute in a form where all path data commands are expressed in terms of the following subset of SVGPathSegtypes: SVG_PATHSEG_MOVETO_ABS (M), SVG_PATHSEG_LINETO_ABS (L), SVG_PATHSEG_CURVETO_CUBIC_ABS (C) and SVG_PATHSEG_CLOSEPATH (z). Thus, if the ‘d’ attribute has an "absolute moveto (M)" and an "absolute arcto (A)" command, then pathSegList will have one SVG_PATHSEG_MOVETO_ABS entry followed by a series of SVG_PATHSEG_LINETO_ABS entries which approximate the arc. This alternate representation is available to provide a simpler interface to developers who would benefit from a more limited set of commands.
