Attribute 4 of producing assembly instance might change when being used in an IO connection

The size of a producing (T2O) assembly instance (attribute 4) changes when being used in an IO connection and the requested size within the forward open is less than the maximum the assembly instance supports.

E.g.: the assembly size is configured to be min = 0, max = 100. The assembly is bound to a connection that only requests 10 bytes in the O2T direction. As soon as the connection is established, attribute 4 of that assembly instance will deliver value 10, even after the connection is closed again.

The size of the assembly instance shall not be influenced by the connection this assembly instance participates in.
