Summary

A display profile document has a low or high priority depending on whether you consider the merge order or the ability to lock as the defining factor.

Without considering locking, the lower numbered display profile document has a lower priority. The lower numbered display profile document gets merged first so the value of a higher priority document overrides the value of a lower priority document. In this sense, the lower numbered document has a lower priority.

However, the lower numbered display profile document can also lock an object so it cannot be affected by a higher numbered document. In this sense, the lower numbered document has a higher priority.
