Document Type Definition for the HyperText Markup Language
6
for Internet Explorer, V 2.0.
8
Author: Mark Buckley <mbuckley@microsoft.com>
10
This markup is based as much as possible on the DTD for HTML 2.0
11
published in the 12/95 IETF working draft. Table markup is based
12
on the table DTD included in the HTML3 DTD, not the 12/95 tables
15
Note that SGML Document Access (SDA) fixed attributes have not
16
necessarily been worked out yet for added elements.
18
Principal changes from the IETF DTD:
20
Took out the HTML.Highlighting and HTML.Forms marked sections.
21
Highlighting and form elements are now always included.
23
Moved entity declarations for common content models together & up
24
top in the DTD to allow for more effective recombination for the
27
Moved DL into %lists for simplification.
29
Added IE HTML extensions and most Netscape extensions.
31
Changes since 2/26/96:
34
Added BGSOUND to HEAD.
