[CONNECT C++] Reading ItemType Data from an Element

I've got an element with an ItemType attached. I want to get the value for a specific property of that ItemType. I can get a DgnECInstancePtr for a specific ItemType that is on the element. The issue is how to get a specific property value. I can use the DgnECInstancePtr and call GetValue(itemValue, index), but the "index" order is not reflective of the order in which those properties were defined/inserted into the ItemTypeLibrary. Further investigation  reveals that there is a PropertyLayout class that may be used to obtain the "index" for a property, but the only way I see to get a PropertyValue is to use the ClassLayout class, which I'm not sure how to get...

It looks like once you have a ClassLayout, you get get a PropertyLayout...

DgnFileP activeDgnFile = ISessionMgr::GetActiveDgnFile();
ItemTypeLibraryPtr newLibrary = ItemTypeLibrary::FindByName(L"Test", *activeDgnFile);
if (newLibrary.IsValid())
{
	ItemTypeP itemType = newLibrary->GetItemTypeByName (L"Air Tunnel");	//nullptr if not found
	if (itemType)
	{
		CustomItemHost host (eeh);
		DgnECInstancePtr itemInstance = host.GetCustomItem (newLibrary->GetName(), itemType->GetName());
		if (itemInstance.IsValid())
		{
			PropertyLayoutCP	layoutCP;	// to see how the properties are indexed ?
			ClassLayoutPtr		classLayoutPtr=ClassLayout::BuildFromClass(???);
			classLayoutPtr->GetPropertyLayout(layoutCP,L"Status"); // ??????
		}
	}
}

So the question is how to determine the "index" for a specific property of an ItemType?
