class_docstr: Defines the attributes of a class:`FeatureStore` tensor; in particular,
  all the parameters necessary to uniquely identify a tensor from the feature
  store.
  
  Note that the order of the attributes is important; this is the order in
  which attributes must be provided for indexing calls. Feature store
  implementor classes can define a different ordering by overriding
  :meth:`TensorAttr.__init__`.
