When Mondrian tools output MDX results as text, such as in the cmdRunner utility, we've been using the same old crappy format for years. For example, the query

select
  crossjoin(
    {[Time].[1997].[Q1],  [Time].[1997].[Q2].[4]},
    {[Measures].[Unit Sales], [Measures].[Store  Sales]}) on 0,
  {[USA].[CA].[Los Angeles],
   [USA].[WA].[Seattle],
   [USA].[CA].[San Francisco]} on 1
FROM [Sales]

is formatted as

Axis #0:
{}
Axis #1:
{[Time].[1997].[Q1], [Measures].[Unit  Sales]}
{[Time].[1997].[Q1], [Measures].[Store  Sales]}
{[Time].[1997].[Q2].[4], [Measures].[Unit  Sales]}
{[Time].[1997].[Q2].[4], [Measures].[Store Sales]}
Axis #2:
{[Store].[All Stores].[USA].[CA].[Los Angeles]}
{[Store].[All  Stores].[USA].[WA].[Seattle]}
{[Store].[All Stores].[USA].[CA].[San  Francisco]}
Row #0: 6,373
Row #0: 13,736.97
Row #0: 1,865
