Ok, so this is a limitation of the MetaInterpreter and not a modeling
problem on my side.
However I found out that (indirectly) attaching lib1 twice works as long as
the entities in this library are abstract and their attributes have set
"Globale Scope" to "false" (the latter requirement I unfortunately only
found out after my first post).

For my problem (ensuring identical attributes of entities in different
mgas), this is sufficient as I can inherit from the (abstract) lib1-entities
in lib2, lib3 as well as test.mga without issues.

Thanks for your help.
