Thanks for the quick reply. Unfortunately it's not practical for us to change the DTD.
A script that runs during validation might do the trick, but I don't know if a validation event macro in XMAX can tell the container that the document is invalid. The 5.5 Programmer's Guide indicates that the Application.ValidationSuccess property works for Author only.
You guys should probably consider some kind of add on validation for this scenario in the DITA editions of Author.
