oreilly-html.dtd
The O'Reilly HTML Extended DTD is an extension of the
"recommended" interpretation of the HTML 2.0 DTD as defined in
RFC 1866. The extensions add the following popular features:
+ Tables
The table model from the now defunct HTML 3.0 DTD has been
used with the following modifications: the content model of
<TD> has been extended to include text (non-block) elements
and the type of the BORDER attribute has been changed to
NUMBER in order to support changes to the border width.
Note: In SGML, the validity of <TABLE BORDER> and
<TABLE BORDER=value> are mutually exclusive. In order to support
<TABLE BORDER=value> in this DTD, it is necessary to make
<TABLE BORDER> invalid. This makes the O'Reilly HTML
Extended DTD backwards-incompatible with HTML 2.0.
+ Modification of browser background and colors through attributes
on the <BODY> element.
+ Support for WIDTH and ALIGN attributes on HR.
+ Support for HEIGHT, WIDTH, BORDER, ALIGN=left and ALIGN=right on IMG.
+ Support for CLEAR attribute on BR.
+ Support for an ALIGN attribute on P.
+ Support for an ALIGN attribute on headings.
+ Support for the <FONT> element.
+ Support for the <CENTER> element.
+ Support for the additional entities: © and .
We use the following DOCTYPE to identify this DTD:
<!DOCTYPE HTML PUBLIC "-//O'Reilly and Associates//DTD HTML Extended 1.0//EN">
In addition, four external entities (files) are referenced by
this DTD:
1. PUBLIC "-//O'Reilly and Associates//DTD HTML 2.0//EN"
The HTML DTD from RFC 1866 with a few slight modifications.
2. PUBLIC "ISO 8879-1986//ENTITIES Added Latin 1//EN//HTML"
The ISO Latin1 entities (referenced by the RFC 1866 DTD).
3. PUBLIC "-//O'Reilly and Associates//ELEMENTS Table Fragment 1.0//EN"
The table elements, extracted from the now defunct HTML 3.0 DTD,
with the modifications noted above.
4. PUBLIC "-//O'Reilly and Associates//ENTITIES Additional HTML 1.0//EN"
Additional entity definitions.
