This is the HTML 4.01 Transitional DTD, which includes
3
presentation attributes and elements that W3C expects to phase out
4
as support for style sheets matures. Authors should use the Strict
5
DTD when possible, but may use the Transitional DTD when support
6
for presentation attribute and elements is required.
8
HTML 4 includes mechanisms for style sheets, scripting,
9
embedding objects, improved support for right to left and mixed
10
direction text, and enhancements to forms for improved
11
accessibility for people with disabilities.

The HTML 4.01 specification includes additional
26
syntactic constraints that cannot be expressed within
30
<!ENTITY % HTML.Version "-//W3C//DTD HTML 4.01 Transitional//EN"
33
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
34
"http://www.w3.org/TR/html4/loose.dtd">
44
The URI used as a system identifier with the public identifier allows
45
the user agent to download the DTD and entity sets as needed.
47
The FPI for the Strict HTML 4.01 DTD is:

"-//W3C//DTD HTML 4.01//EN"
51
This version of the strict DTD is:
53
http://www.w3.org/TR/1999/REC-html401-19991224/strict.dtd
55
Authors should use the Strict DTD unless they need the
56
presentation control for user agents that don't (adequately)
59
If you are writing a document that includes frames, use
62
"-//W3C//DTD HTML 4.01 Frameset//EN"

This version of the frameset DTD is:

The BORDER attribute sets the thickness of the frame around the
801
table. The default units are screen pixels.
803
The FRAME attribute specifies which parts of the frame around
804
the table should be rendered. The values are not the same as
805
CALS to avoid a name clash with the VALIGN attribute.
807
The value "border" is included for backwards compatibility with
808
<TABLE BORDER> which yields frame=border and border=implied
809
For <TABLE BORDER=1> you get border=1 and frame=implied. In this
810
case, it is appropriate to treat this as frame=border for backwards
811
compatibility with deployed browsers.
813
<!ENTITY % TFrame "(void|above|below|hsides|lhs|rhs|vsides|box|border)">
816
The RULES attribute defines which rules to draw between cells:

"none" if BORDER is absent or BORDER=0 otherwise "all"

<!--================== Document Frames ===================================-->
953
The content model for HTML documents depends on whether the HEAD is
954
followed by a FRAMESET or BODY element. The widespread omission of
955
the BODY start tag makes it impractical to define the content model
956
without the use of a marked section.
