9.6. Sample SGML Open Entity Catalog for HTML

   The SGML standard describes an "entity manager" as the portion or
   component of an SGML system that maps SGML entities into the actual
   storage model (e.g., the file system). The standard itself does not

Top      Up      ToC       Page 66 
   define a particular mapping methodology or notation.

   To assist the interoperability among various SGML tools and systems,
   the SGML Open consortium has passed a technical resolution that
   defines a format for an application-independent entity catalog that
   maps external identifiers and/or entity names to file names.

   Each entry in the catalog associates a storage object identifier
   (such as a file name) with information about the external entity that
   appears in the SGML document. In addition to entries that associate
   public identifiers, a catalog entry can associate an entity name with
   a storage object identifier. For example, the following are possible
   catalog entries:

9.7. Character Entity Sets

   The HTML DTD defines the following entities. They represent
   particular graphic characters which have special meanings in places
   in the markup, or may not be part of the character set available to

Top      Up      ToC       Page 67 
   the writer.

9.7.1. Numeric and Special Graphic Entity Set

   The following table lists each of the characters included from the
   Numeric and Special Graphic entity set, along with its name, syntax
   for use, and description. This list is derived from `ISO Standard
   8879:1986//ENTITIES Numeric and Special Graphic//EN'.  However, HTML
   does not include for the entire entity set -- only the entities
   listed below are included.

    GLYPH   NAME    SYNTAX  DESCRIPTION
    <       lt      &lt;    Less than sign
    >       gt      &gt;    Greater than signn
    &       amp     &amp;   Ampersand
    "       quot    &quot;  Double quote sign

9.7.2. ISO Latin 1 Character Entity Set

   The following public text lists each of the characters specified in
   the Added Latin 1 entity set, along with its name, syntax for use,
   and description. This list is derived from ISO Standard
   8879:1986//ENTITIES Added Latin 1//EN. HTML includes the entire
   entity set.

10. Security Considerations

   Anchors, embedded images, and all other elements which contain URIs
   as parameters may cause the URI to be dereferenced in response to
   user input. In this case, the security considerations of [URL] apply.

   The widely deployed methods for submitting forms requests -- HTTP and
   SMTP -- provide little assurance of confidentiality.  Information
   providers who request sensitive information via forms -- especially
   by way of the `PASSWORD' type input field (see 8.1.2, "Input Field:
   INPUT") -- should be aware and make their users aware of the lack of
   confidentiality.

12. Acknowledgments

   The HTML document type was designed by Tim Berners-Lee at CERN as
   part of the 1990 World Wide Web project. In 1992, Dan Connolly wrote
   the HTML Document Type Definition (DTD) and a brief HTML
   specification.

   Since 1993, a wide variety of Internet participants have contributed
   to the evolution of HTML, which has included the addition of in-line
   images introduced by the NCSA Mosaic software for WWW. Dave Raggett
   played an important role in deriving the forms material from the
   HTML+ specification.

   Dan Connolly and Karen Olson Muldrow rewrote the HTML Specification
   in 1994. The document was then edited by the HTML working group as a
   whole, with updates being made by Eric Schieler, Mike Knezovich, and
   Eric W. Sink at Spyglass, Inc.  Finally, Roy Fielding restructured
   the entire draft into its current form.

   Special thanks to the many active participants in the HTML working
   group, too numerous to list individually, without whom there would be
   no standards process and no standard. That this document approaches
   its objective of carefully converging a description of current
   practice and formalization of HTML's relationship to SGML is a
   tribute to their effort.

14. Proposed Entities

   The HTML DTD references the "Added Latin 1" entity set, which only
   supplies named entities for a subset of the non-ASCII characters in
   [ISO-8859-1], namely the accented characters. The following entities
   should be supported so that all ISO 8859-1 characters may only be
   referenced symbolically. The names for these entities are taken from
   the appendixes of [SGML].
