   SGML purists should excuse the use of the term "DTD" in this file to represent
   DTD-related information which is not exactly a DTD itself.
   
   The C modular structure doesn't work very well here, as the dtd is partly in the .h and
   partly in the .c which are not very independent.  Tant pis.
