This is HTML 4.01 Strict DTD, which excludes the presentation
3
attributes and elements that W3C expects to phase out as
4
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.

http://www.w3.org/TR/1999/REC-html401-19991224
25
The HTML 4.01 specification includes additional
26
syntactic constraints that cannot be expressed within
33
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
34
"http://www.w3.org/TR/html4/strict.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 Transitional HTML 4.01 DTD is:
49
"-//W3C//DTD HTML 4.01 Transitional//EN"
51
This version of the transitional DTD is:

http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd
55
If you are writing a document that includes frames, use

"-//W3C//DTD HTML 4.01 Frameset//EN"

This version of the frameset DTD is:

http://www.w3.org/TR/1999/REC-html401-19991224/frameset.dtd

<!-- IETF HTML table standard, see [RFC1942] -->
666
The BORDER attribute sets the thickness of the frame around the
667
table. The default units are screen pixels.
669
The FRAME attribute specifies which parts of the frame around
670
the table should be rendered. The values are not the same as
671
CALS to avoid a name clash with the VALIGN attribute.
673
The value "border" is included for backwards compatibility with
674
<TABLE BORDER> which yields frame=border and border=implied
675
For <TABLE BORDER=1> you get border=1 and frame=implied. In this
676
case, it is appropriate to treat this as frame=border for backwards
677
compatibility with deployed browsers.
679
<!ENTITY % TFrame "(void|above|below|hsides|lhs|rhs|vsides|box|border)">
682
The RULES attribute defines which rules to draw between cells:
684
If RULES is absent then assume:
685
"none" if BORDER is absent or BORDER=0 otherwise "all"
688
<!ENTITY % TRules "(none | groups | rows | cols | all)">
