For more complex Design Templates, the User may wish to reference other Design Templates as sub-equipment to make up part of the overall design instance.
For example, when instanced in a design, sub-equipment can be referenced.

Each Valid Value (VVALUE) under the data element stores a reference to a Specification Component (SPCO) which has its Template Reference (TMPR) pointing to a TMPL representing a specific vessel end (as illustrated for the default setting).
The Sub-equipment (SUBE) elements shown in the hierarchy are created under the Equipment, by default, when the properties are set for the Design Template instance.
To reference to sub-equipment, make sure the correct Design Template is highlighted in the Template Browser.
On the Design Templates tab, in the Modify group, click Property Definitions to display the Define Template Properties window.

The Property part of the Define Template Properties window allows the User to define the identification fields of the Design Template property.
