The HTML DTD -- software interface in libwww
HTML DTD - SOFTWARE INTERFACE
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.
