<!-- html-hj.dtd Document Type Definition for the HyperText Markup Language (HTML DTD) for Sun Microsystems Corp. HotJava environment Date: 24 Jul 95 Revisions made by: Mark Gaither (markg@hal.com) Original Author: Dave Raggett <dsr@hplb.hpl.hp.com> I have taken the HTML 3.0 DTD dated 16 Mar 95 and added the APP element introduced by Sun Microsystems Corp. to accomodate their Java/HotJava WWW application environment.--><!ENTITY % HTML.Version "-//Sun Micorsystems Corp.//DTD HotJava HTML//EN" -- Typical usage: <!DOCTYPE HTML PUBLIC "-//Sun Micorsystems Corp.//DTD HotJava HTML//EN"> <html> ... </html> -- ><!--================== Flags for Marked Sections ==========================--><!ENTITY % HTML.Recommended "IGNORE" -- Certain features of the language are necessary for compatibility with widespread usage, but they may compromise the structural integrity of a document. This feature test entity enables a more prescriptive document type definition that eliminates the above features. --><![ %HTML.Recommended [ <!ENTITY % HTML.Deprecated "IGNORE">]]><!ENTITY % HTML.Deprecated "INCLUDE" -- Certain features of the language are necessary for compatibility with earlier versions of the specification, but they tend to be used an implemented inconsistently, and their use is deprecated. This feature test entity enables a document type definition that eliminates these features. --> <!ENTITY % HTML.Obsoleted "IGNORE" -- The XMP, LISTING and PLAINTEXT tags are incompatible with SGML and derive from very early versions of HTML. They require non- standard parsers and will cause problems for processing documents with standard SGML tools. --><!--================== Imported Names =====================================--><!ENTITY % Content-Type "CDATA" -- meaning a MIME content type, as per RFC1521 --><!ENTITY % HTTP-Method "GET | POST" -- as per HTTP specification --><!ENTITY % URI "CDATA" -- The term URI means a CDATA attribute whose value is a Uniform Resource Identifier, as defined by "Uniform Resource Identifiers" by Tim Berners-Lee aka http://info.cern.ch/hypertext/WWW/Addressing/URL/URI_Overview.html aka RFC 1630 Note that CDATA attributes are limited by the LITLEN capacity (1024 in the current version of html.decl), so that URIs in HTML have a bounded length. --><!ENTITY % REAL "CDATA" -- real numbers (not in SGML) --><!ENTITY % SHAPE "CDATA" -- Shape of hotzone in image. All coordinates are assumed to be numbers in the range 0 to 1 and interpreted as fractional width/height and measured from the top left corner of the associated image. The attribute value is a string taking one of the following forms: "default" Used to define a default link for the figure background. "circle x, y, r" (x, y) define the center and r the radius. "rect x, y, w, h" (x, y) defines upper left, and w and h the width and height. "polygon x1, y1, x2, y2, ..." Given n pairs of x, y coordinates, the polygon is closed by a line linking the n'th point to the first. Intersecting polygons use the non-zero winding number rule to determine if a point lies inside the polygon.I --><!-- 3.0 Parameter Entities --><!ENTITY % heading "H1|H2|H3|H4|H5|H6"><![ %HTML.Obsoleted [ <!ENTITY % preformatted "PRE | XMP | LISTING">]]><![ %HTML.Deprecated [ <!ENTITY % list "UL | OL | DIR | MENU"> <!ENTITY % blockquote "BLOCKQUOTE | BQ">]]><!ENTITY % list "UL | OL"><!ENTITY % blockquote "BQ"><!ENTITY % preformatted "PRE"><!-- The CLASS attribute is used to subclass HTML elements for rendering purposes, when used with style sheets, e.g. DSSSL lite --><!ENTITY % attrs -- common attributes for elements -- 'id ID #IMPLIED -- as target for hrefs (link ends) -- lang CDATA "en.us" -- ISO language, country code -- class NAMES #IMPLIED -- for subclassing elements --'><!-- SGML standard forces different NAMES for all attribute values in the same element, regardless of the attribute name! As a result CDATA is used for CLEAR attribute to avoid clash with ALIGN attribute.--><!--When text flows around a figure or table in the margin, you sometimes wantto start an element like a header, paragraph or list below the figure ratherthan alongside it. The CLEAR attribute allows you to move down unconditionally: clear=left move down until left margin is clear clear=right move down until right margin is clear clear=all move down until both margins are clearAlternatively, you can decide to place the element alongside the figure justso long as there is enough room. The minimum width needed is specified as: clear="40 en" move down until there is at least 40 en units free clear="100 pixels" move down until there is at least 100 pixels free The style sheet (or browser defaults) may provide default minimum widths foreach class of block-like elements.--><!ENTITY % needs -- Attributes for controlling text flow.

The style sheet controls the numbering style: a) whether the parent numbering is inherited, e.g. 5.i.c where 5 is the current sequence number for H1 headers, and 1 is the number for H2 headers and 3 for H3 headers. b) what style is used for current sequence number e.g. arabic, upperalpha, loweralpha, upperroman, lowerroman or a numbering scheme appropriate for the current language The skip attribute is used to skip over sequence numbers for items which have been left out of the list, e.g. skip=3 advances the sequence number past 3 omitted items. The seqnum sets the sequence number to a specified value. Note that the style sheet may take advantage of the sequence number for higher level headers. The dingbat or src attributes may be used to specify a bullet like image to be placed adjacent to the header. Defining this in the header element simplifies the document markup and avoids the need to use the clear or needs attribute in the following element to prevent it flowing around this image.--><!ELEMENT ( %heading ) - - (%text;)+><!ATTLIST ( %heading ) %attrs; align (left|center|right|justify) #IMPLIED %needs; -- for control of text flow -- seqnum NUMBER #IMPLIED -- starting sequence number -- skip NUMBER 0 -- skip seq nums for missing items -- dingbat ENTITY #IMPLIED -- dingbat entity from HTMLicons -- src (%URI;) #IMPLIED -- bullet defined by graphic -- %url.link; -- standard link attributes -- nowrap (nowrap) #IMPLIED -- disable wordwrap -- ><!ELEMENT TITLE - - (#PCDATA) -- The TITLE element is not considered part of the flow of text.
