Wow, that's amazing, this is something that I had on my list but because I didn't have time I have always postponed and only implementing the requirements of the moment.
So first of all thank you very much for collaborating with us, second one thank you so much for using asciidoctor, and if you have any other feedback not only about AsciidoctorJ but about Asciidoctor (things that may change, or would fit better in your environment), don't hesitate to write them.
Again thank you very much and please send the pull request. :)
Cool, in documentation if you can add a use case of use, I mean why could be interesting to get information from AsciiDoc document, it will help other users to understand the need of having access to that elements.
