This requirement needs to remove the HVol VES and Fault VES as both of them are covered by separate requirements and also both of them are not part of PnP. Here is the new requirement proposed by Trevor:
A PNF MUST support the pnfRegistration VES event which is required to integrate with ONAP’s PNF Plug and Play capabilities.

Requirement: R-106240
target: PNF
keyword: SHOULD
introduced: casablanca
updated: el alto
The following VES Events SHOULD be supported by the PNF: pnfRegistration VES Event, HVol VES Event, and Fault VES Event. These are onboarded via he SDC Design Studio.
Note: these VES Events are emitted from the PNF to support PNF Plug and Play, High Volume Measurements, and Fault events respectively.

A PNF MUST support the pnfRegistration VES event which is required to integrate with ONAP’s PNF Plug and Play capabilities.
