After which type properties are not exported in case they are not specified in the user-defined property sets file.

Since 23.3.0, to export type properties for the IFCElement, for example, 
a user should include "IFCElementType" in the proper .txt file.

In the following case only instance properties from "testPset" will be exported
"PropertySet: testPset T IfcElement" 

In order for the type properties to be exported, the type entity should be specified IFCElementType as follows:
"PropertySet: testPset T IfcElement, IfcElementType"
