Message arguments must always be constants or attributes of the sender. ✘ All the parameters of the operation must be matched by message arguments. ✘ A message argument should be of exactly the same type as the parameters of the corresponding operation. ✘ The message arguments must the same type as the parameters of the corresponding operation or a subset of the parameters of the corresponding operation. ✔

a scheduler that chooses the next lifeline on which to run ✘ a specific lifeline that selects a resource from a resource pool ✘ a construct to select one lifeline out of all the lifelines in the diagram ✘ an expression selecting one out of a set; a general indexing mechanism ✔

Events are ordered from top to bottom in a sequence diagram. Events are ordered from top to bottom of a lifeline in a simple sequence diagram. When messages represent operation calls, their sending and receiving events coincide in time. The send event of a complete message comes before the receive event of the same message. The start event of an execution occurrence will coincide in time with the event representing the call of that operation.

The interaction is no longer valid. ✘ A message is stopped short of its reception. ✘ The object represented by a lifeline terminates. ✘ The behavior of a lifeline halts within this diagram. ✔
