Options passed to the ValueStorageHandler storeValueToFile
method.
If set to true
and the value storage handler is able to detect lossy conditions (e.g., storing to a directory
but there aren't enough value storage handlers for all properties), the value storage handler will reject with an
error if a loss of data condition is detected.
By default, storage is best-effort and values that aren't covered by handlers are ignored.
