The way I think it I cannot see how it corrupts relation roles. This
complement to the role would be optional, not compulsory. So, up to
now, what have been mapped without it (complement) can be seen in one
of the following 2 ways:
1 - As an incomplete information, though it doesn't change the meaning
of the role in the relation;
2 - As an already complete info, because not necessarily all stops
would have this complementary information, because there are stops
with not exact time to arrive/leave whose situation can have their
times stipulated.

> Perhaps this is something that could be proposed later.

For sure, that's the reason I'm already voting yes.
