>+ These changes are because the the SVG list interface has changed from 
>+ SVG1.1 and SVG2. See:
>+ https://www.w3.org/TR/SVG11/types.html#InterfaceSVGLengthList
>+ https://www.w3.org/TR/SVG/types.html#TermListInterface
>+
>+ The biggest difference is related to inserting an newItem into a list
>+ and the newItem is attached to another list. SVG1.1 states that the
>+ newItem from its old list before adding it to the new list. SVG2 states
>+ that only a copy of the newItem will be inserted.
