HTML Plus DTD - Software Interface</H1>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.<P>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.
