It's compounded by the fact that we need to (a) interoperate with Java Exceptions (b) assume that SAX will be put alongside packages that have yet another set of Exceptions. I spent yesterday afternoon hacking the new SAX/AElfred including the extraction of error messages and transferring them to display of nonwf documents. My blunderings weren't pretty (I failed to realise that one test example threw FileNotFoundException rather than a parsing error, and couldn't understand why I couldn't extract the SAXException message). But I think I can work with the current SAX. (I was one of those who suggested SAX should 'wrap' Exceptions, so pillory me.) >but I can think of several possibilities >in addition to the old solution and the current solution, any of which I >think would be an improvement over the current solution: [... workable solutions snipped ...] I am sure that David will look at these carefully - I think the final decision is essentially his - he has put in *so* much work and got enough public and private mail to make a balanced decision. David must feel like he's on a never-ending marathon - if he feels that SAX1.0gamma is 'it', I think we should accept it. [Every finalisation has bits that someone doesn't like, even XML...] P.
