2009/3/20 Quinn, Dan <[email protected]> > Hi, > > Is it possible to mix dsl language and regular rule syntax in a rule > file? I am trying to do this, but my rules won't compile. The "unable to > expand" error is returned during compilation. I tried adding [*][]"{anything}" > = "{anything}" to the dsl file to fix this, but that didnt work.
