on reviewing this issue and reviewing the specification - we found a number of issues - the specification says "Historians are not required to be able to store arrays. Optional ConformanceUnits exist to indicate if they support storage of arrays. If a Historian does store arrays, it may not support returning an index range in an array, it may only provide the entire array. ConformanceUnits are provided to indicate if a Historian supports index ranges." - which mean the ConformanceUnits are missing - and these test case should not be in this existing ConformanceUnit, but a different one (that currently does not exist) - will confirm this issue and then enter a related new issue for part 7 - Also if IndexRanges are not supported in general - then is it an ErrorCode (which one)? or is just the entire array returned? this is a UA working group discussion.

Next the test script should be checking if the data in the range that it is running for has the correct dimension for the test. {note if indexranges are not supported}
