OK, passing the list of extensions through the new routine is indeed a
cleaner approach. One point of detail is that instead of doing this
part:
+       /* Handle the CASCADE option. */
+       if (d_cascade)
+               cascade = defGetBoolean(d_cascade);
+       else
+               cascade = false;
You may as well just initialize cascade to false at the beginning of
the routine and update it only if d_cascade is defined.

Attached are as well changes for the documentation that I spotted in
earlier reviews but were not included in the last version sent by Petr
yesterday. Feel free to discard them if you think they are not
adapted, the patch attached applies on top of Petr's patch.
