When changing the item's attributes through this property, the physical item should be immediately modified if it exists. If it does not exist, the attributes should be cached and applied whenever this item is created.
Some types of items may not expose attributes; in this case, DoHasAttributes should return false to prevent DoAttributes from being called.
