Message number: 043
Message text: &1 New interval &2 &3 &4
The program has determined that a new number range interval is required
for a successful generation of the mapping proposals.
The program generates mapping proposals on basis of subobject mappings.
It maps all intervals of the source subobject to the same intervals of
the target subobject. If target subobject does not have an interval with
the same number or year (for year-dependent objects) the program will
try to create it.
