Yes!  Thanks for spotting this, I've now fixed it in CVS.

ZOOM already does support it; the problem is that Zebra doesn't --
there's a known bug whereby that call corrupts the registers.  So
until that's fixed (and it is on the list), which you _can_ send a
"drop" request from ZOOM, you'd better not!  :-)

When using shadow registers in Zebra.

Don't know -- that's one for Adam to answer.

I've not heard of "recordIdNumber" before, but I am guessing that it
just means "the unique ID of the record, as extracted from the record
itself using the rules specified in the Zebra configuration".  As you
know, every record in a Zebra database is identified by a, uh,
identifier.  That can either be drawn from the record itself (which
is probably what you want when adding MARC records that have IDs in
them), or you can specify an ID explicitly when you add the record.

I don't know about case scenerios -- again, Adam would have a better
handle on that.

> When would it be useful to populate the databaseName option?

Always, when creating or destroying a database.

No.  You might have a connection pointing at one database, and want to
create or destroy a different one.

There's no "connect to multiple databases" functionality in ZOOM, no.
(What would such functionality mean?)

Sorry -- again, I don't know.  Adam's yer man.
