>It does not seem ethical or even legal to take open >source software -- even if you were the original >architect -- and use it for your own purposes. You may want to reread the Apache license. I believe it's fairly explicit about saying that anyone -- contributor or not -- can produce a product spinning off from Apache code in whole or in part, as it stands or modified, as long as the Apache contribution is properly credited. This is true open source; if someone wants to take the source and run they can do so, and if we don't like that it's up to us to make our version more attractive than theirs. I'd much prefer to bring Jacek's work back into the Xalan community, assuming he comes up with some useful ideas. But I don't think barking at him's likely to achieve that. (Speaking of the license -- I've just noticed that the license currently reserves the name Xalan, but does not reserve the name XSLTC. It might be a Very Good Thing if either we or Jacek renamed our XSLT compiler to avoid confusion, and we might want to think about either changing our name or our license or both to provide better coverage.)
