Please DO NOT do this!!
I've discussed this the XMP team and they do NOT recommend the
inclusion of a "binary blob" of data inside of XMP, and ESPECIALLY
NOT the MakerNote data. That should remain as a binary block inside
the other formats. That is how Adobe Creative Suite handles it and
we would recommend that for compatibilty you do the same.
