Optional
cardCard number on the Palm OS device (typically 0).
Optional
dbPre-fetched DlpDBInfoType for the database.
On Palm OS 2.x and earlier, there is no way to get a DlpDBInfoType for a single database as DlpFindDBByName is not supported. Instead, we need to use DlpReadDBList to read DlpDBInfoType for all databases on the device. So if doing a bulk backup, we should call DlpReadDBList first and pass in the corresponding DlpDBInfoType in each call to readDb().
Optional
includeWhether to include deleted / archived records.
Options to readDb and readRawDb.
