+ 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 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: &copy; and &nbsp;.
+
+ 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.
+
+ An appropriate SGML Open catalog file for this DTD is:
+
+ PUBLIC "-//O'Reilly and Associates//DTD HTML 2.0//EN"
