About checking and assigning (creating) identity being different:
Quite correct. The difference between the two is context. Identity checking always assumes/implies the more specific context of e.g. change characteristics. Identity assignment, OTOH, can basically only assume some upper bound of numbers in the supported pool of identities, and little more (some life-cycle information for aging may also be available etc.).
