+This component translates column data into references, i.e. "inflating"
+the column data. It also "deflates" references into an appropriate format
 for the database.
 
 It can be used, for example, to automatically convert to and from
 L<DateTime> objects for your date and time fields.
 
+It will accept arrayrefs, hashrefs and blessed references (objects),
+but not scalarrefs. Scalar references are passed through to the
+database to deal with, to allow such settings as C< \'year + 1'> and
+C< \'DEFAULT' > to work.
