[DDI-SRG] Question on byte order in ProprietaryRecordLayout and/or binary data formats

[Joachim Wackerow]

Pascal,

I think it is a property of the data file (or storage) not the data. For 
example the summary statistics are a property of the data regardless how 
the data is stored.

If it is in RecordLayout and ProprietaryRecordLayout, it should be 
sufficient.

Anyway, can you please file a bug for this, I'm going home now.
