:type items: dict or dict-like object
:param items: A dictionary-like object.  The keys of the dictionary are
the item names and the values are either:
* dictionaries of attribute names/values, exactly the
same as the attribute_names parameter of the scalar
put_attributes call.  The attribute name/value pairs
will only be deleted if they match the name/value
pairs passed in.
* None which means that all attributes associated
with the item should be deleted.
