		 * The DomParser is a close-to (but not entirely) conforming XML parser
		 * based on regular expressions. It will take any XML fragment and
		 * return a lightweight JS structure that is similar to (but not
		 * exactly) the DOM specification.
		 * 
		 * Getter and setter methods are NOT available; the goal was to keep the
		 * resulting object model entirely JS-like.
		 * 
		 * All node types but document fragments are supported; all nodes
		 * support getElementsByTagName and getElementsByTagNameNS (with short
		 * names byName and byNameNS). The document node supports getElementById
		 * (byId), and all nodes support a supplimental
		 * childrenByName/childrenByNameNS method as well.
		 * 
		 * The object model is intended to be a READONLY format; mutation events
		 * are NOT supported, and though you can change properties on a
		 * node-by-node basis, certain operations are not supported (such as
		 * changing the ID of an element).
