I have code to read an ARRIRAW image based on the ARRIRAW Image File Structure and Interpretation Supporting Deferred Demosaicing to a Logarithmic Encoding document from the SMPTE site. It works fine for AlexaLF images but when I use ARRIRAW Converter to extract a MiniLF image from an MXF wrapper the my code does not produce a correct image. I have noticed two differences in the
headers:

1) In the Image Data Information Subheader the Subheader Version is 1 for the AlexaLF and 66 for the MiniLf. Is there any documentation for version 66 of this subheader?
2) In the Image Data Information Subheader the Defined Content Length is 68 in he MiniLF but 60 in the AlexaLF. Does this mean that the some of the reserved area has been used? If so, how
should it be interpreted?
