I'm not sure exactly what you're trying to do, but one option is to add a new type of DOMException:
http://trac.webkit.org/browser/trunk/Source/WebCore/dom/DOMExceptions.in Another option is to customize the message from an existing exception (here are the DOMCore exceptions): http://trac.webkit.org/browser/trunk/Source/WebCore/dom/DOMCoreException.cpp If you show me the spec you're trying to implement, I might have a more concept suggestion of the best way to implement it.
