2 W3C Document Type Definition for the HyperText Markup Language
3 This version is code named Wilbur, and also as "HTML 3.2".
4
5 Draft: Tuesday 21-May-96
6
7 Author: Dave Raggett <dsr@w3.org>
8
9 This is subject to change, pending final approval by the W3C
10 member companies.
11
12 HTML 3.2 aims to capture recommended practice as of early '96
13 and as such to be used as a replacement for HTML 2.0 (RFC 1866).
14 Widely deployed rendering attributes are included where they
15 have been shown to be interoperable. SCRIPT and STYLE are
16 included to smooth the introduction of client-side scripts
17 and style sheets. Browsers must avoid showing the contents
18 of these element Otherwise support for them is not required.
19 ID, CLASS and STYLE attributes are not included in this version
20 of HTML.
21
22 The next version of HTML after Wilbur is code named Cougar and
23 will add support for <OBJECT>, client-side scripting, style
24 sheets, and extensions to fill-out forms.

265 <!--
266 This tag is supported by all java enabled browsers. Applet resources
267 (including their classes) are normally loaded relative to the document
268 URL (or <BASE> element if it is defined). The CODEBASE attribute is used
269 to change this default behavior. If the CODEBASE attribute is defined then
270 it specifies a different location to find applet resources. The value
271 can be an absolute URL or a relative URL. The absolute URL is used as is
272 without modification and is not effected by the documents <BASE> element.
273 When the codebase attribute is relative, then it is relative to the
274 document URL (or <BASE> tag if defined). <TEXTFLOW> avoids the problems
275 with SGML mixed content. It can always be omitted *except* when the APPLET
276 element hasn't any content. White space, comments and PARAM elements
277 don't count as content for this purpose. TEXTFLOW was introduced into
278 the DTD to satisfy SGML parsers, but is ignored by current Web browsers.
