Ok, I was looking through nithfile.c, am I correct in understanding that the only TRE supported for saving is BLOCKA, and that each additional TRE needs to be handled
individually?

I need to add support for the following TREs. But I don't really need to add new SDE headers, but preserve the original values as read
using GDALGetMetadataItem.

SENSRA
AIMIDB
ACFTB

Is there an easy way to save back an TRE that was read using GDAL (/0 escaped string) or should I pull out all the fields from the string, and then reassemble them in a function as is done for BLOCKA?
