Public Comment: svg:viewBox issues

Now reads (in full): The svg:viewBox attribute establishes a user coordinate system inside the physical coordinate system of the shape specified by the position and size attributes. This user coordinate system is used by the draw:points and svg:d attributes, as well as by the attributes of <draw:enhanced-geometry> element and its child elements which specify coordinates. The syntax for using this attribute is the same as the [SVG] syntax. The value of the attribute are four numbers separated by white spaces, which define the left, top, right, and bottom dimensions of the user coordinate system.
