ObjectDb.conf Defaults

Is it expected that all objectdb.conf entries are optional and when they are not provided defaults are used?  It appears that that is the case for all documented entries, except for 4 entries under "General".

<objectdb>
<general>
  <!-- error if missing <temp path="$temp/ObjectDb" threshold="64mb" /> -->
  <!-- error if missing <network inactivity-timeout="0" /> -->
  <!-- ok if missing <url-history size="0" user="false" password="false" /> -->
  <!-- error if missing <log path="" max="8mb" stdout="false" stderr="false" /> -->
  <!-- error if missing <log-archive path="$objectdb/log/archive/" retain="90" /> -->
  <!-- ok if missing <logger name="*" level="info" /> -->
</general>
</objectdb>

No. Some settings are required in a valid objectdb.conf file (although the objectdb.conf file itself is optional). This may change in future versions of ObjectDB.
