  Fix MID-6786 preliminarily

Here we replace very ugly hack that uses t:ItemDeltaType to pass values
from library function to its clients by a little less ugly use
of t:ItemType.

The whole "solution" is still very hacky, and should be reviewed.

Overall, the support for class-less containers and their values has
to be improved.
