negative.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 your own converter that creates string content running in {uri-repo}[AsciidoctorJ] these steps are required:
  
  - Implement the converter as a subclass of `org.asciidoctor.converter.StringConverter`.
    Annotate it as a converter for your target format using the annotation `@org.asciidoctor.converter.ConverterFor`.
  - Register the converter at the `ConverterRegistry`.
  - Pass the target format name to the `Asciidoctor` instance when rendering a source file.
