The subtypes of IfcPropertyTemplateDefinition are declared within a project context. The uppermost template definition (e.g. the IfcPropertySetTemplate including several IfcPropertyTemplate's) should be related to the context, either IfcProject, or IfcProjectLibrary, using the inherited HasContext inverse attribute.
