Most document style policies are established simply by using the template documentation framework. However, by applying some conventions to the document source structure, community members will be able to work across more documentation projects. The recommended documentation structure guidelines are as follows: The head book file should be named with the prefix "bk_". The document versioning as defined by the releaseinfo tag in the main book file bk_xxx should be named "Revision N.N", not "Version N.N" or simply "N.N" Chapters files should be named with the prefix "ch_". Section and sub-section files should be named with the prefix "sec_". Appendix files should be named with the prefix "app_". Figures source and images should be placed in the figures sub-directory for the document.
