   Now that I've got all of the frontend and back-bdb config
keywords implemented (read-only) I'd appreciate some feedback on
the schema etc. before moving ahead to doing the write
operations.  Having gone thru all of this config stuff, a lot of
other ideas came to mind:  slurpd replica configuration should
probably have both an included and excluded attrs list, like
syncrepl does. It would greatly simplify the exclusion
processing in repl.c. Also, deleting the an_oc_exclude flag from
the AttributeName structure would simplify things too.  I wonder
if replication (syncrepl and slurpd) directives should be in
their own objects, subordinate to the database object.  I find
writing schemas unbearable without using OID macros. It would be
nice to use them more overtly, using unqualified names (e.g.,
DirectoryString instead of my current OMsDirectoryString).  Some
of the back-config retrieval functions will no-op if they're in
their default values, but many of them just return a value,
default or not. The goal was
