00085 // reference counted DOM classes - DOMStrings, Nodes (including subclasses),
00086 // and NamedNodeMaps.
00087 //
00088 // Usage Example:
00089 // DomMemDebug initialState; // Captures allocation totals
00090 // ... // Test code performs DOM
00091 // ... // operations here.
00092 //
00093 // DomMemDebug exitState; // Captures post-test state.
00094 // ExitState.printDifference(initialState); // Display leaks.
