    Set an attribute for a collection or item.

    Origin must be Signed and must conform to the namespace ruleset:

    • CollectionOwner namespace could be modified by the collection Admin only;
    • ItemOwner namespace could be modified by the maybe_item owner only. maybe_item should be set in that case;
    • Account(AccountId) namespace could be modified only when the origin was given a permission to do so;

    The funds of origin are reserved according to the formula: AttributeDepositBase + DepositPerByte * (key.len + value.len) taking into account any already reserved funds.

    • collection: The identifier of the collection whose item's metadata to set.
    • maybe_item: The identifier of the item whose metadata to set.
    • namespace: Attribute's namespace.
    • key: The key of the attribute.
    • value: The value to which to set the attribute.
