Andreas Gal's domjs project ( https://github.com/andreasgal/dom.js ) has an
interesting idea:  a separate class for "leaf nodes", which cannot have
children.

I wonder if this might be worth adding to the DOM4 spec, by splitting the Node
interface into two parts:  
(1) A LeafNode interface which implements all the current Node's interface
properties except firstChild, childNodes, lastChild, insertBefore, appendChild,
replaceChild, and removeChild.
(2) A Node interface which inherits from LeafNode and adds those extracted
properties.

interface LeafNode : EventTarget;
interface Node : LeafNode;

It might make text nodes, comments, etc. - nodes that can't have children -
somewhat simpler.

I'm only asking for consideration of the idea.
