- Separate function to merge a child attribute into matching inherited attribute: The logic to merge a child attribute into matching inherited attribute in MergeAttribute() is only applicable to regular inheritance child. The code is isolated and coherent enough that it can be separated into a function of its own. - Separate function to merge next parent attribute: Partitions inherit from only a single parent. The logic to merge an attribute from the next parent into the corresponding attribute inherited from previous parents in MergeAttribute() is only applicable to regular inheritance children. This code is isolated enough that it can be separate into a function by itself. These separations makes MergeAttribute() more readable by making it easier to follow high level logic without getting entangled into details.
