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.  <EM>Tant pis!</EM> There are a couple of HTML-specific
utility routines also defined. <P>

This module is a part of the <A
HREF="http://www.w3.org/pub/WWW/Library/">
W3C Sample Code Library</A>.

<H2>Entity numbers</H2>

The entity names are defined in the C file.  This gives the number of them.

<H2>Element Numbers</H2>

<PRE>
#define HTML_ENTITIES 67

Must Match all tables by element!  These include tables in <A
HREF="HTMLPDTD.c" NAME="z1">HTMLPDTD.c</A> and code in <A
HREF="HTML.c" NAME="z0">HTML.c</A>.<P>

Differences from Internet Draft 00: HTML, H7,PLAINTEXT LISTINGand XMP
