The one scenario that bothers me with this is: - the parser always supplies both XML 1.0 names and cooked namespace declarations - the application is namespace-aware and only interested in the cooked namespace information - the application iterates over all attributes using getLocalName(int). In this scenario, the fact that the parser is supplying XML 1.0 raw names in addition to cooked namespace declarations will force the application to check whether getLocalName is returning null (indicating a namespace declaration) and, if so, ignore the attribute. This seems to be the one case where a namespace-aware application that is being driven by a parser that provides cooked namespace information is affected by whether or not the parser also provides XML 1.0 raw names. This seems a bad thing, but so far I haven't been able to think of a fully satisfactory solution. > This is kind-of painful Indeed. Although I think your proposal is quite reasonable, and although I don't have anything better to propose right now, I can't say I feel altogether comfortable with it. I think we should continue to explore other possible solutions. If it's possible to have a completely new org.xml.sax2 package, then more radical solutions are possible. For example, I think there are good arguments for moving to a interface DocumentHandler { void startElement(StartElementEvent event) void endElement(EndElementEvent event) ... } style interface. This makes it much easier to evolve the interface in the future. For example, a SAX3 that added support for XML Schemas could just add additional methods to StartElementEvent and EndElementEvent and thus remain compatible with SAX2.
