[wildfly-dev] Remove Xalan?

We are keeping a (old) fork around for Xalan. Now and then the question pops whether we can backport more from upstream. Rather I want to rid of it at all as I don't want to maintain forks of third party projects and I don't see Xalan releasing soon with anything we would upstream. Can we remove Xalan? (Maybe we have some weird dependency on specifics.) What should be its replacement? Filed https://issues.jboss.org/browse/WFLY-4704 to note any decisions. Carlo
