a) test case would be nice
b) NH doesn't make a distinction between properties and their declaration
order. That means that it get calls GetProperty("Name") and use whatever
comes.
In the scenario that you describe, I don't think it is documented what will
be the order to return that.
c) simplest option, add another property with different name.
