utility vessel type

also called vessel type

Which open household holding vessel this is — a basin (a wide, shallow open vessel for washing or soaking, the pricelist's dozens of round/Tyre/Pyramid basins and wash basins), a tub (a deeper basin — a size/depth gloss on the same open form, e.g. an Apple/Florida tub) or a bucket (a deep open vessel carried by an over-top bail; a pail). These pieces share the UtilityVessel slot-profile (an open utility vessel) and differ only by this role name plus capacity, shape, material and colour, so they are VALUES here rather than classes (the drinkware_type / dinnerware_type / food_storage_type fold). A bucket folds here (its bail is a low-variety presence feature; a mop bucket's wheels, a tap or a steel-bail grade are answerable for only some buckets and mint a child/property WHEN seeded). A water-storage drum is NOT a value here — it adds an exclusive required closure and is the class WaterStorageDrum (no double-count, the Bowl/LunchCarrier-excluded precedent). Concern identity (a basin vs a bucket is a different listing, NON-axis-eligible); optional (a WaterStorageDrum inherits it unfilled).
