It would be useful to be able to indicate *for individual messages*
what role the sender is considering the recipient to be playing.
This would be useful when it would be too cumbersome to use a separate
lifeline to represent the recipient playing that role (e.g. when the
separate lifeline would only be needed for a single message in the
UML associations allow an association end to be annotated with an
"interface specifier" using the format ": ClassifierName". This
"indicates the behavior expected of an associated object by the
related instance". Perhaps we could allow this notation to be used
on interaction diagrams as well, i.e. a message could look like
| a | | b: Role1 |
| :Role2 |
It might be necesary to restrict this usage, e.g. maybe Role2 should
be a sub-role of Role 1.
