P & P Software has released XSLTdoc 1.0, a free-as-in-speech (GPL) Javadoc-like tool for XSLT stylesheets. Instead of using comments, it uses elements in the http://www.pnp-software.com/XSLTdoc namespace. These are top-level elements that appear before each documented top-level XSLT element. The processor is itself implemented in XSLT 2.0. The XSLT stylesheets are not complete onto themselves. A config file is also required, though mostly this just replaces what would be provided by command line arguments in javadoc. However, truly JavaDoc like documentation should be able to generated purely from the XSLT stylesheets themselves, without any extra files needing to be consulted.
