This is HTML 4.0 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 4.0 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 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)">

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