As the BPMN library of ADOxx.org contains 'RTF' and 'HTML' documentation. These documentations need an extension in the modeltype definitions. This means if you define new modeltypes you have to add a MODE called 'Documentation' to your modeltype definition by adding the following line of code.
1MODE "Documentation" from:all no-modeling
The extension 'no-modelling means that this MODE will not be shown in the option "Modes" in the Modelling Component.
