Hi Andrew (or anyone else that cares to answer),

I've missed out on hearing about incompatabilites between MARCXML and
NXDBs.   Can you explain?  Is this just eXist and Sleepycat, or are
there others?  I seem to recall putting a few records in X-Hive with no
problems, but I didn't put it through any paces.

Also, if there was a cure to the problems with MARCXML (I'm sure we can
all think of some), what would you suggest to help alleviate the problems?
