As one can see, the Display element is set to the German translation of the concept as this is the only designation explicitly provided. In order to provide an English designation, too and to set the Display to the english designation, we only need to add the following OntoDL code:
<hr>
<pre>
default lang=en
#obligation Überschrift 2 => set me.Designation[lang=en] == me.Code
#obligation Überschrift 3 => set me.Designation[lang=en] == me.Code
</pre>
<hr>
The defined obligations are executed after the text of the given style sheet has been processed. It directs the OntoDL interpreter to set the English name of the concept to the value of its code. By defining English as the default language, the OntoDL Interpreter selects the English designation as the display name (unless a display name is explicitly given).
