是否有可能在Modelica中有条件地设置方程属性？(Is it possible to conditionally set equation attributes in Modelica?)

 我正在研究一个包含多个子系统的大型模型，以及相当多的变量/方程式。 我一直在子系统上使用protected属性，因此在模拟结果中只能看到系统级结果。 这样可以更轻松地在Dymola仿真选项卡或FMU输入/输出中查找系统级结果。 但有些情况下，能够查看子系统的完整详细程度也是很好的。 
 
 是否可以基于布尔参数或其他方式有条件地应用受保护的属性？ 
 
 例如，是否可以执行下面的伪代码？ 
 
// Parameter that sets whether or not to use the protected attribute on subsystems.
parameter Boolean useProtected = true;

// Conditionally define the subsystem with or without protected attribute
if (useProtected) then
  protected subsystem subsystem1 = ...
else
  subsystem subsystem1 = ...
end if;
 
 谢谢，贾斯汀 

I am working on a large model that includes multiple subsystems, and a fairly large number of variables/equations. I have been using the protected attribute on subystems so that only the system level results are visible in the simulation results. This makes it easier to find system level results in the Dymola simulation tab or in FMU inputs/outputs. But there are cases where it would be nice to be able to see the full level of detail for the subsystems also.
 
Is it possible to conditionally apply the protected attribute based upon a Boolean parameter, or some other way?
 
For instance, is it possible to do something like the pseudocode below?
 
// Parameter that sets whether or not to use the protected attribute on subsystems.
parameter Boolean useProtected = true;

// Conditionally define the subsystem with or without protected attribute
if (useProtected) then
  protected subsystem subsystem1 = ...
else
  subsystem subsystem1 = ...
end if;
 
Thanks, Justin
