I haven't had this happen to me in practice. I agree that the SGML
declaration mechanism sucks but I've never had it silently fail on me.
Usually it vociferously fails! But that's neither here nor there: both
specs handle their optional features badly. SGML hides its option
declarations too far from the data and XML doesn't have option
declarations at all!
