         * This is a "first one wins" strategy. I.e. the first value found for any given result
         * attribute will be assigned to the user. Different values found in subsequently queried
         * attribute sources will be ignored. Suitable if uP-local attributes should always take
         * precedence.
         *
         * Other options (all in the same package):
         *   - MultivaluedAttributeMerger - Collects values from all DAOs into lists (does not
         *     filter out duplicate values, though)
         *   - ReplacingAttributeAdder - "Last one wins" strategy. I.e. the opposite of
         *     NoncollidingAttributeAdder.
