Our template is created under the Diagram Overview element, and therefore the scope is already on the Diagram Overview element we working on. We can then using the diagramId property to from Diagram Overview shape and pass it into DiagramProperty node to switch the scope to the diagram it referring to.

<DiagramProperty property="diagramId">

Now we are in the scope of the associated diagram. We can now output the details of the diagrams, such as name, image, etc.

<Text style="@heading+">Associated Diagram: </Text>
<Property property="name" style="@heading"/>
<ParagraphBreak/>
<Image/>
