Select not null values in a single column in MDX

There is a keyword 'NON EMPTY' in MDX which returns all rows where at least one column has a non null value in it. But if we instead want to select all rows where value of a single column is not null then we can use the function NONEMPTY() like so:

SELECT  
  { 
    [Measures].[Hits] 
   ,[Measures].[Subscribers] 
   ,[Measures].[Spam] 
  } ON COLUMNS 
 ,{ 
    NonEmpty 
    ( 
      [Geography].[Country].Children 
     ,[Measures].[Subscribers] 
    ) 
  } ON ROWS 
FROM [Blog Statistics];
