positive.code: == Writing a custom converter
  
  For output formats that are not natively supported by Asciidoctor it is possible to write an own converter in Java.
  To get an own converter running in {uri-repo}[AsciidoctorJ] these steps are required:
  
  - Implement the converter as a subclass of `org.asciidoctor.converter.AbstractConverter`.
  - Register the converter with a well defined backend name at the `ConverterRegistry`.
