Arguemnts:
value -- 'pytis.data.Value' instance to be converted.
'lcg.LocalizableDateTime' instances may be included in LCG element's export
result and will be automatically formatted according to the target locale
during LCG export. The function returns a string if the conversion is not
possible (see below) or necessary (for null values).
The conversion is applied only to base pytis.data.Date type and not to its
descendants. The derived classes may customize the export and since we are
replacing the type's export here, the customized export would be igored.
Thus it is safer to limit special handling to direct pytis.data.Date
instances here, althought it is unpleasant, that derived types are not
localized automatically.
