The guidance in Annex V for the Financial Assets Held for Trading data point, Annex V.Part 2.25 says that interest income - other assets "may include" interest income from balances at central banks and several other asset classes . Does this mean this is required, ie the balance "must include" interest income from balances at central banks and the other specified asset classes , or that this is optional?

This item may include interest income related to cash and cash balances at central banks and non-current assets and disposal groups classified as held for sale as well as net interest income from net defined benefit asset.
