[New Model]: Shared aspect for BPN(L/S/A)

[tom-rm-meyer-ISST]

Model Description

BPNs are used very often. From personal knowledge I can say: I do often copy them. As Johannes proposed extracting them in PR #295, we already created PR #297.

I copied the texts from the CX standard.

Relevant Standards

CX-0010
