Introduction to DocBook XML DTD
        
        
          The DocBook XML DTD-4.5 package
          contains document type definitions for verification of XML data
          files against the DocBook rule set. These are useful for
          structuring books and software documentation to a standard allowing
          you to utilize transformations already written for that standard.
        
        
          This package is known to build and work properly using an LFS-7.7
          platform.

            Note
          
          
            The package source is distributed in zip format and requires unzip. You should create a
            directory and change to that directory before unzipping the file
            to ease the removal of the source files after the package has
            been installed.

            requested in the System Identifier, you need to add additional
            statements to the catalog files. If you have any of the
            DocBook XML DTD's referenced
            below already installed on your system, remove those entries from
