German to English Law/Patents Patents examinations

This sentence comes from a summary of an examination for patentability. The numbers in question do not refer to the patent being examined, but to another patent used to evaluate patentability.

Behälter (Fig.2), insbesondere Druckbehälter, mit einem rohrförmigen Gehäuseteil (Fig.2, Pos.12), in dem ein Deckelteil (Fig.2, Pos.10) festlegbar ist, wobei in einer Ausnehmung (Fig.2, Pos.18) auf der Innenseite des Gehäuseteiles zumindest teilweise Anlagesegmente (Fig.2, Pos.24,28) eingelegt sind, an denen sich das Deckelteil in seinem Einbauzustand abstützt, und dass mindestens ein Festlegemittel (Fig.2, Pos.30) vorgesehen ist.

Is it possible that Pos. here does not mean position, but rather reference number?
The parts are not moving, there is not reference to an open or closed position, instead Pos. is used to indicate a specific piece of the device. Normally, I would assumed that it is a reference number, but I can't find evidence that Pos. is used in this way.
