Attribute merging strategy that joins all the individual elements of both attribute values in a single array. When
merging two attributes, attribute values that are not ArrayAttrValues are converted to an ArrayAttrValue
whose value is a sequence with a single element: the value of AttributeValue prior to the conversion.
