Great.
Bug report and patch is ideal. There are patches to the SDM so you
can tell it that patch#N fixes bug#M etc, but they are not live on
OpenACS.Org (Ben -- are they working well enough to use here?).
So for now, just submit a bug report against the SDM module, and in
the description say "fixed by Path #whatever". I think that's the
best we can do with the SDM as it now stands.
