Appendix E. The XHTML 1.0 DTD
The XHTML 1.0 standard is formally defined
as three XML Document Type Definitions (DTDs): the
Strict DTD, the Transitional DTD, and the
Frameset DTD. These DTDs correspond to the respective HTML 4.01 DTDs,
defining the same elements and attributes using XML instead of SGML
as the DTD authoring language.
The Strict DTD defines only those elements that are not deprecated in
the HTML 4.01 standard. Ideally, everyone would create XHTML
documents that conform to the Strict DTD. The Transitional DTD
includes all those deprecated elements and more accurately reflects
the HTML in use today, with many older elements still in common use.
The Frameset DTD is identical to the Transitional DTD, with the
exception that the document <body> is
replaced by the <frameset> element.
Since the HTML Transitional DTD is the one upon which this book is
based, it is only appropriate that we include the corresponding XHTML
DTD. Note that we have reprinted this DTD verbatim and have not
attempted to add extensions to it. Where our description and the DTD
deviate, assume the DTD is correct.
<!--
Extensible HTML version 1.0 Transitional DTD
This is the same as HTML 4.0 Transitional except for
changes due to the differences between XML and SGML.

The frame attribute specifies which parts of the frame around
the table should be rendered. The values are not the same as
CALS to avoid a name clash with the valign attribute.
