Codegen Module
The stylesheets in this module generate C source and header files for xmlroff from the XML for the XSL 1.0 Recommendation (http://www.w3.org/TR/2001/REC-xsl-20011015/xslspec.xml, included in the distribution as 'xslspec.xml').
The generated files are not guaranteed to be drop-in replacements for the existing xmlroff source code and header files, since many of the xmlroff source code and header files have had manual modifications.
You should use Emacs's ediff or some other diff/merge utility to compare the generated file and the existing version and only change what should be changed.
The exception are the .c and .h files created for a property that has just been added to codegen-info.xml: since the property's files didn't exist before, you can just copy the generated files to the xmlroff source code.
