How to identify if a subsystem is an autosar block in matlab

Hi there, i need to differ some subsystem blocks in matlab. To check if a subsystem is a stateflow or a subsystem is pretty easy by checking the ErrorFcn-Parameter. The Problem I have is, how to check if a subsystem is an autosar block. The ErrorFcn is empty, Masks aren't used anymore on default by MatLab. But there has to be a way to check this. I hope that somebody can tell me, which parameter contains a checkable Value for autosar blocks. Pls help me :) Atm I am using MatLab 2015. Thank you for your help :) I wish U a nice christmas time :) Greetings Manuel
