title: With the xproc file, how to debug/trace step-by-step in oxygen?
body: <p>I'm going to learn Xproc language. Does the oxygen software have the capability to debug/trace step-by-step with Xproc script? and how can do it? Thanks. My oxygen editor version is 21.0.</p>
  
  <p>Or is there another IDE that does that?</p>
