Many thanks for the answers. So if we upgrade to 3.4, I'll have to modify 
kohadb to take out the (varchar 32) constraint? So far, we have endeavoured 
to remain "faithful" to the Master version, but cataloguing our serials is 
an uphill challenge.

Perhaps easier to add specific items.xyx - I don't think the XML will be 
problematic, but wonder if these are all concatenated for OPAC display? 
(e.g. at the moment 520 $a and $b ARE concatenated. I'm looking for a way 
to undo this.)

This sounds like a possible solution - instead of "local" specialized uses 
(German remapping of
995$j to 952$i in this case) getting into the Master, surely it is more 
logical to leave more flexibility? I don't think everyone has the time to 
follow all bugs (I certainly missed this one), maybe the development team 
could assure us that 952 $[A-Z] are fully working and available for local 
use, while 952 $[a-z] are for Koha use?

Best - Paul
