--  XHTML 1.0 (HTML 4.0-Based XML Version) Catalog Data File

    Revision:  @(#)XHTML1.cat 1.19 99/04/01 SMI

    This is the catalog data file for various versions of the XHTML DTD.
    You do not need to use the file names listed here, and do not need 
    to use the filename method of identifying storage objects at all.

    See "Entity Management", SGML Open Technical Resolution 9401 for detailed
    information on supplying and using catalog data. This document is available
    from OASIS at URL:

C.4. Common Declaration

In order to take advantage of the XHTML DTD Modules, DTD authors needs to define the content model for their DTD. XHTML provides a variety of tools to ease this effort. They are defined in the following support modules. See Extending XHTML for more information on using these and the Modules in custom DTDs

<!--  This is the driver file for version 1.0 of the XHTML Strict DTD.

      Please use this formal public identifier to identify it:

      Please use this URI to identify the default namespace:   

          "http://www.w3.org/TR/1999/REC-html-in-xml"

      For example, if you are using XHTML 1.0 directly, use the FPI 
      in the DOCTYPE declaration, with the xmlns attribute on the 
      document element to identify the default namespace:

        <?xml version="1.0" ?>
        <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
