SGML (/caedmon/html/sgm/readme.txt) This directory system contains the Standard General Markup Language (SGML) master files. All other versions of the edition, including the print text, have been generated from these files. Only proofing corrections have been made independently in the different versions. These files are not intended for display to the end user, though they may prove of use in some applications. A discussion of the encoding practices followed may be found in the Conventions and Encoding chapter in all versions of the display text. The files have all been validated against the TEI P4 standard. Additional and modified elements are listed in the Conventions and Encoding chapter. Conversion to HTML and PDF has been accomplished using custom stylesheets for the Multidoc SGML Browser and custom scripts. These are found in the /caedmon/html/sgm/stylesheets/ directory. Future editions of the text will be in XML and processed using XSLT. The SGML text makes heavy use of entities to record readings from the primary sources. The method used is discussed in a forthcoming (2005) article in HumanIT. Because of a flaw in the Multidoc Browser, Unicode references in the SGML text begin with the dollar sign ($) rather than the usual ampersand-x-hash prefix (&#x).
