• unresolved_externalF

  public static void unresolved_externalF(String name)

  External functions that cannot be resolved are replaced with a call to this method. This method will generate a runtime errors. A good stylesheet checks whether the function exists using conditional constructs, and never really tries to call it if it doesn't exist. But simple stylesheets may result in a call to this method. The compiler should generate a warning if it encounters a call to an unresolved external function.
