README This directory contains the current version of the DocBook DTD, its documentation, an SGML declaration, and some sample files. As of 17 December 1993 the latest revision of the DTD is version 2.1. As of 17 December 1993 the documentation for the DTD version 2.1 consists of a "Guide" that includes an alphabetical list of elements, with definitions, in PostScript. A sample Chapter and sample RefEntry (man page) are also provided, and the alphabetical list of elements is provided in SGML as well as PostScript. The entity file "orathree" contains local entities for use with these examples. DocBook 2.1 is an expanded and revised version of 1.2.2 (which is also to be found here, for reference). Instances conforming to 1.2.1 will require some changes to conform to 2.1. More documentation may be made available as time permits. Suggestions for improving the documentation are welcome. The DTD does not establish detailed rules for the usage of elements. This is a matter for editors and writers to deal with. Please note that the DTD has an associated SGML declaration. To get all of the files relevant to version 2.1, obtain the files named docbook.2.1.shar and docbook.ps.Z.
