It's described in the UML 1.3 Spec, but Rose doesn't really support it.
You could turn on sequence numbering, and then add a text comment to the
diagram indicating how a series of messages is repeated.
There is also a notation for looping and branching described in the
context of collaboration diagrams. Collaboration diagrams are
translatable to sequence diagrams, so some people (including me) use
this loop notation in both kinds of diagrams. It's a bit of a hack, but
you can manually prepend this notation to message names in the sequence
diagram.
OMG-UML V1.3
3.71.2.4 Sequence expression
...
The recurrence represents conditional or iterative execution. This
represents zero or more Messages that are executed depending on the
conditions involved. The choices are:
�*� �[� iteration-clause �]�an iteration
�[� condition-clause �]�a branch
An iteration represents a sequence of Messages at the given nesting
depth. The
iteration clause may be omitted (in which case the iteration conditions
are unspecified). The iteration-clause is meant to be expressed in
pseudocode or an actual programming language, UML does not prescribe its
format. An example would be: *[i := 1..n].
