If you use CreateListEntries. The descrition I made above, was in conjunction
with not using CreateListEntries.

Compability. However, I will have to do a little research in the Fiasco
sources in this issue.

If CreateListEntries is specified

Again if CreateListEntries is specified. Otherwise, it is IMO quite
useful if the old entry remains unchanged, if an element is
unititialized.

Predefined value = initial content?
