Yes, but whitespace-only nodes are very common in XML formatted for 
human consumption e.g.

<foo>
	<bar>Hello</bar>
	<bar>Hi</bar>
</foo>

I count 3 whitespace-only nodes (even after normalize). Those nodes are 
not useful to the application some I'm wondering about the canonical 
way of removing them (without writing the [admittedly simple] code myself).
