 Description: Makes sure the field $name is defined and its $value
              is non empty. If @legal_values is defined, this routine
-             also checks whether its value is one of the legal values
-             associated with this field. If the test is successful,
+             checks whether its value is one of the legal values

+             the default valid values for this field obtained by
+             C<get_legal_field_values($name)>. If the test is successful,
              the function returns 1. If the test fails, an error
              is thrown (by default), unless $no_warn is true, in which
              case the function returns 0.
 
 Params:      $name         - the field name
