I took MyFaces 1.2.0 and stripped somewhere around 80% of the classes.  Pretty much ripped out everything but org.apache.myfaces.config package.  Doing this gives you just enough to parse versions 1.0, 1.1 and 1.2 of faces-config files using two lines of code.

ByteArrayInputStream bais = new ByteArrayInputStream(testFacesConfig.getBytes());
dispenser.feed(unmarshaller.getFacesConfig(bais, null));

Here are the costs of going this route.  This introduces a dependency on digestor, commons logging, beanutils and commons collections.  It also means we have to maintain the myfaces-stripped jar until the config stuff gets moved into the new myfaces commons project (which probably won't be released before JSFUnit).  It also means we have to ping a lawyer because I have never done this before (change ASF artifact, release under LGPL).

Let me know your thoughts.  I timeboxed this at an hour so I don't have a lot of emotions behind going this route.  Part of me feels like just benching this until after the release.
