        Is it supported to materialize a LOB locator outside the transaction in which it was created?

        Again, part of the trickiness here is the fact that this is largely driver dependent.

        NOTE: all database I have tested which Dialect.supportsExpectedLobUsagePattern() also support the ability to materialize a LOB outside the owning transaction...
