+ describes this property only in terms of [Objects](pcdm:Object) and [Collections](pcdm:Collection), but formally defines its domain and range as Aggregations.
+ While this might have only been a modelling convenience, this ontology preserves the broader definition, to allow the use of this term without needing a firm stance on whether something is (or isnĀ¦t) an Object or Collection as would have it.
