A Flex-PaP is a PaP defined by some fixed parameters (mainly times at the border/handover points between IMs) and the indication of a range of flexible parameters. (E.g. shows standard running time, location and duration of stops for intermediate / operational points).

A Network PaP is part of the way how to calculate the priority in case of conflicting PaP-requests and not a path product as Flex-PaP and Fix-PaP. Some successive PaP segments are defined as Network PaP in order that in a first step of the priority calculation only those segments are taken in account.

These two expressions are no specific path products - they describe ways how a Fix-PaP or/and a Flex PaP is used within a request and are not path products.
