Amendment: If any of the roles is used in an OTE, which in turn is substituted by a role with a TC, all roles under the OTE are considered mandatory. |

This illustrates an OT with two OTE's. One of the OTE's is involved in a TC and one is not. This results in one optional role instead of two. |

(To determine the optionality of roles, is performed during an update on the OTFT, related TC's or adding expressions. This routine is no longer called during GLR or afterwards to honor the optionality of roles from the conceptual model.) |

The old FCOIM book shows a diagram on Pg217 (Fig6.19) in which Role 4 is substituted by both O1 and O2, therefor Role 2 remains optional. This causes the previous comment on this ticket to require further nuance. |
