If we can implement this setProperty(name, value) and getProperty(name) methods on WSDLFactory interface we can use them to specify Logger option. Some of the XML parsers already use this approach and this will help to add any new properties without changing API. I suggest specifically WSDLFactory interface for this because we need to support at least following 3 use cases for logging . 1. Reading WSDL 2.0 document using WSDLReader. 2. Writing WSDL 2.0 document using WSDLWriter. 3. Create or modify WSDL using Element level API and eventually Component level API too . ( e.g. - FWSDLFactory#newDescription() and add Elements and so on) WDYT.......?
