Major Description
RUTA makes all types that are known to the CAS available by their short name. This means that a type may be available when the script runs in one aggregate but not when it runs in the other.
For example, the following script will sometimes work and sometimes not work depending if the aggregate in which it is executed knows about a type with short name MyType or not:
PACKAGE com.example.ruta;
W{->MARK(MyType)};
I would expect only types from the typesystems declared in the RUTA script to be allowed.
