 Each XML file contains references to two other files: logtalk.dtd, a DTD file describing the XML file structure, and a XSL style sheet file responsible for converting the XML files to some desired format like HTML. The name of the XSL file can be changed in the configuration files via the lgt_file_name/2 predicate. The default value is lgtxml.xsl, a XSL file that enables Logtalk XML files to be viewed directly in a web browser. The HTML output refers a CSS file, logtalk.css, that specifies how the HTML code will be rendered. The three default files are contained in the xml sub-directory in the Logtalk installation directory. This directory may also contain other files for specific XSLT processors or for converting XML to other formats besides HTML. Please read the NOTES file included in the directory for details.

 By default, all file references use relative paths, assuming that the .xml documentation files and the .dtd, .xsl, and .css files reside in the same directory. This can acomplished either by copying the DTD and style files to the your application compiling directory or by using file aliases or symbolic links, depending on the operating system that you are using.
