title: How to get the name of invisible attributes and user defined Hierarchies using MDX?
body: <p>I have a cube with some dimensions. There I have a dimension 'Product' which has some attributes and user defined hierarchies hidden. I do not know which attributes are hidden.
  Is there a way to write an MDX to get the invisible attributes and user defined hierarchies?
  I can get the name by other ways. But I want to know the way to get using MDX.</p>
