Like any other object that isn't currently accessible by QOF, it is untouched.
If the target book has SX, it is not altered, if the import book has SX, they
are not merged.
If the definitions are added, I see no reason why they would not merge
successfully. The same for commodity and pricedb etc. I've added support for
the business objects and it's all part of the testing. I've got to get this
sub-account problem sorted and then I can test with other objects.
The currency is only set because of the handler in druid-merge.c - left as a
plain qof_book_merge, imported objects cannot have a commodity defined as no
commodities are yet accessible to QOF.

No, there are no SX's involved in the merge code - the merge only uses QOF
objects as described. Plus the example books that I'm using for testing do
not contain SX's (either in the import or target books) - I test the GnuCash
merge druid code using the example account trees.
