  ^[1]^ Page backgrounds do not currently work when using AsciidoctorJ PDF.
  This limitation is due to a bug in Prawn 1.3.1.
  The limitation will remain until AsciidoctorJ PDF upgrades to Prawn 2.x (an upgrade that is waiting on AsciidoctorJ to migrate to JRuby 9000).
  For more details, see http://discuss.asciidoctor.org/Asciidoctor-YAML-style-file-for-PDF-and-maven-td3849.html[this thread].
