+ /**********************************************************
+ * 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).
