attribute. The keyword value can be a literal, a set, or a callable. A
literal must match the attribute exactly. Given a set, the attribute value
must be in the set. A callable is called with the attribute value. If an
attribute is specified as a keyword argument but not present in the
attributes, the result is False."""
