+### Can I validate $modelValue instead of a $viewValue? [#272](https://github.com/huei90/angular-validation/pull/272)###
 
 Yes, adding `use-view-value="false"` attribute forces to use $modelValue instead of a $viewValue for evaluation when form is submitted. By default $viewValue is used. This need raises from a need of localized number inputs, which have to be stored in a $viewValue as a string (e.g. "2 000,0"), however in a $modelValue they are stored as a properly formatted number (2000). This can be done e.g. by using a custom directive with properly specified $formatters and $parsers.
