ForAnyValue:ArnNotEquals

Warning:

In spite of the name difference ForAnyValue: ArnNotEquals behaves exactly the same as ForAnyValue: ArnNotLike. Switch to ForAnyValue: ArnNotLike so people don't ask later what in the world you were thinking.

ForAnyValue: ArnNotEquals

ForAnyValue: ArnNotEquals compares a list of ARNs in a request to a list of ARN patterns in your policy. The policy values can include asterisks (*) to match multiple characters and question marks (?) to match a single character within an ARN segement. Wildcards cannot be used to span ARN segment, so the partition, service, region, account, and resource must all be present in your policy value, even if they are all wildcards. The comparision is case sensitive.

To match a request, the context key must exist in the request and at least one ARN in the request must NOT match any of ARN patterns in your policy.

You can use policy variables in the value of this operator.
