Only possible hitch in my proposed final solution is that some elements (<g> and <text>) had code that allowed any child type. If I'm going to put code into sp-item to write <title> and <desc> in Plain SVG mode, I need to explicitly disallow the serializing of <item> and <desc> in <g>'s write method.
