Thanks for this quick feedback.

It seems that we expect different data processing also for the shown test case.

The SmPL construct “<+... … ...+>” supports a search for code parts
which occur at least once.
Thus it seems that the specified search pattern needs be duplicated before
if you would like to find code which should occur at least twice.
I would appreciate if undesirable duplication of search patterns can be avoided here.
