What's a doctype?  SGML had the idea that you could get to the DTD from 
the Public or System identifier, and that's all you could get to 
(automatically).  RDDL tries to deal with the reality that a "document 
type", if such a thing exists, involves more than one schema in one 
language.  To be fair, the SGML people always said that the DTD formally 
included all the human-readable documentation; RDDL is trying to 
automate that.  There was a brief wave of enthusiasm a couple of years 
ago from people who wanted to repeat SGML's mistake of placing the 
schema (i.e. a bundle of syntax constraints) at the center of 
everything, but we seem to have gotten over that. -Tim
