anchor.diff:  when applicable. For example this HTTP port config entry will appear as:
   
   
  -[source]
  +[source,properties]
   --
   #
   # The HTTP port
  
positive.code: 
  The syntax for this is `%{profile}.config.key=value`. For example if I have the following:
  
  ----
  quarkus.http.port=9090
  %dev.quarkus.http.port=8181
  
negative.code: Then you need to include fully qualified class name of converter in a service file `META-INF/services/org.eclipse.microprofile.config.spi.Converter`.
  If you have more converters simply add their class names in this file as well. Single fully qualified class name per line, for example:
  
  [source]
  ----
  org.acme.config.MicroProfileCustomValueConverter
  org.acme.config.SomeOtherConverter
