WESTIM and emergency repair for reefer containers

I have never been a big fan of ISO 9897 EDI messages, mainly because of the lack of documentation and standardization. 

Recently, I have gathered info to report emergency repair for reefer containers in WESTIM EDI message and here is the output from some carriers. 

CMA CGM

In WESTIM, it is possible to report if a container is full or empty through CUI segment.
If the full empty indicator in CUI03 is L (full container) then this will trigger an emegency repair.

Esample: CUI+++L'

COSCO SHIPPING

In WESTIM, it is possible to report the container material (eg. aluminium, steel, etc.) through ERI segment. 
If the material code in ERI01 is B, then this will trigger an emegency repair.

Esample: ERI+B+MAN:01+ACEP'

GRIMALDI LINES

In WESTIM, it is possible to report extra information about the container throught FTX segments. 
If you report a FTX segment, between the TMA and UNT segments, with FTX01=CDX and FTX02=EMERGENCY REPAIR, then this will trigger an emergency repair. 

Esample: TXT+CDX+EMERGENCY REPAIR'

That's the 'short list' but I have, at least, other 3 different processes to implement for other carriers...

I would be very curious to collect your feed-back about this topic: do you use DESTIM rather than WESTIM? In case you go for WESTIM, how do you report emergency repair for reefer containers?
