xsltproc, Saxon or Xalan: http://www.sagehill.net/docbookxsl/InstallingAProcessor.html
Installing Saxon on Linux. Is JAXP 1.3 required? And then how would I test it anyway?
Could install Xalan. But it's already included with Java:
java org.apache.xalan.xslt.EnvironmentCheck
Why can't xemacs' xlst-process mode find any xslt processor?
