A visa application for a travelling family that includes a toddler but where the visa rules say each person must have an individual application 

This is a common scenario for many Australian visa types.  Some authorised delegate (eg Mum) has to do the application for the toddler but still present the toddlers credentials 

Any use?

Using authentication of identity, role, or attributes to make an access decision often leads to a confused deputy vulnerability.
