The RichFaces Comoponent Reference uses a docinfo.xml file  to include docbook metadata in the generated docbook via the <bookinfo> tag.
To include this output with asciidoc I can use the `-a docbook` command option, where there is a naming convention  for the associated docinfo file. Using this same command option with asciidoctor, the docinfo is not included.
Bug? Feature Request? User error on my part?
