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. 

#ifndef HTMLDTD_H
#define HTMLDTD_H

#include "HTUtils.h"
#include "SGML.h"

Element Numbers

Must Match all tables by element!
These include tables in HTMLDTD.c
and code in HTML.c . 

typedef enum _HTMLElement {
	HTML_A, 	HTML_ADDRESS,
	HTML_B,		HTML_BLOCKQUOTE,	HTML_BODY,
	HTML_BR,
	HTML_CITE,	HTML_CODE,	HTML_COMMENT,

Attribute numbers


Identifier is HTML_<element>_<attribute>.
These must match the tables in HTMLDTD.c
!

#define HTML_A_REL		2
#define HTML_A_REV		3

Start anchor element
It is kinda convenient to have a
particulr routine for starting an
anchor element, as everything else
for HTML is simple anyway.

On entry
targetstream poinst to a structured
stream object.

name and href point to attribute
strings or are NULL if the attribute
is to be omitted.

extern void HTStartAnchor PARAMS((
		HTStructured * targetstream,
		CONST char *  	name,
		CONST char *  	href));


#endif /* HTMLDTD_H */





Specify next ID to be used
This is anoter convenience routine,
for specifying the next ID to be
used by an editor in the series z1.
z2,...

extern void HTNextID PARAMS((HTStructured * targetStream, int n));
