Do we have any components built on Xerces/Xalan C++? It's a while since I've built anything on them (I prefer libxml2/libxslt), but my recollection is of Xerces upgrades NOT being drop-in replacements for anything. In which case, any dependencies need to be thoroughly tested with any proposed update. > http://xml.apache.org/xalan-c/whatsnew.html#xml4c says Xalan-C++ 1.10 > is compatible with Xerces-C++ 2.7 and nothing higher. > > http://xerces.apache.org/xerces-c/releases_plan.html page says > "Further releases in the 2.x.y line are currently not anticipated". > So, > it is better to go with the 3.x version. > > There's no definitive release plans for Xalan. > In this thread http://www.nabble.com/XML-Xerces-Xalan- > td22637253.html , > which discusses about the same issue, David (I suppose he maintains > the project) > recommended to use the trunk version with Xerces-C 3.x. I guess the somewhat-conflicting advice is aimed at end-users who want particular versions of Xerces OR Xalan rather than both. > So, should I go with > > 1.

One more option: Xalan 1.10 + Xerces 2.x + (separate) Xerces 3. Bear in mind that since Xerces-2 --> Xerces-3 breaks API-compatibility, it'll also break users applications built on Xerces-2. We can't just abandon Xerces-2, regardless of whether we offer Xerces-3. -- Nick Kew
