Thanks Peter! I have read the documentation, but forgot about that condition.

The simplest solution in your situation would be:
NP{PARTOFNEQ(NP) -> UNMARK(NP)};
(PARTOFNEQ: part of, but not equal)
If it gets more complicated, then something with a loop and/or
additional types is necessary:
BLOCK(forEach) Test{} {
ANY+? Test{-> UNMARK(Test)};
Test{-> UNMARK(Test)} ANY;
}
Best,
Peter
