Action: opened

PR body:
"""
De-duplicate ACI attributes and permissions

Ensure uniqueuess in attributes and permissions in the ACI class.

A set() is not used because it doesn't guarantee order which ends up
causing cascading and unpredictable test failures. Since all we
really need is de-duplication and not a true mathematical set iterating
through the list is sufficiently fast, particularly since the number
of elements will always be low.
