+data      - compressed or uncompressed file attribute data
+
+If flag & EB_BE_FL_NATURAL, the data is not compressed; this optimisation is
+necessary to prevent wasted space for files with small attributes (which
+appears to be quite common on the Advanced Access DR9 release).  In this
+case, there should be ( ef_size - EB_L_BE_LEN ) bytes of data, and full_size
+should equal ( ef_size - EB_L_BE_LEN ).
+
+If the data is compressed, there will be ( ef_size - EB_L_BE_LEN ) bytes of
+compressed data, and full_size bytes of uncompressed data.
+
+If a file has absolutely no attributes, there will not be a 'Be' extra field.
+
+The uncompressed data is arranged like this:
+
+attr_name\0 - C string
+struct attr_info (big-endian)
+attr_data (length in attr_info.size)
