As described in https://datatracker.ietf.org/doc/html/draft-li-apn-framework-04#section-5, the APN requirements include APN Attribute Conveying Requirements and APN attribute Handling Requirements.
In the APN attributes, the carrying of the APN parameters is optional as stated in https://datatracker.ietf.org/doc/html/draft-li-apn-header-00#section-3. The typical APN parameters are the network performance requirements such as bandwidth, latency, etc.
If a hop cannot meet the APN requirements, which would mean that the hop cannot handle the APN attributes, then it will be up to the local configuration. We can explore more on this topic, but generally the flow needs to be forwarded without any interruption, probably in a default mode.
