I don't think a node will ever have a tag name that is an attribute name. Or am
I misunderstanding something.

Oops, it is my mistake. It looks SVGTextPositioningElement doesn't have tag
name. So, I add a virtual function to SVGElement to check if a node is
SVGTextPositioningElement lie SVGContentElement.
