Introduce an option which would notify a user that the value entered should match the specified format.
If the user input matches the mask +1 (999) 99 99 then the editor will have a value +1 (777) 88 99 and the question value will have a value 17778899 if saveMaskedValue is false and +1 (777) 88 99 value if saveMaskedValue is true.
If the user did not enter a complete value and exits the editor or the default value does not match the mask, then the value +1 (777) 88 __ will be displayed in the editor and the question value will have a value 177788 if saveMaskedValue is false and +1 (777) 88 value if saveMaskedValue is true.

When should an error message indicate that the entered value does not match the mask? When leaving the editor, when trying to go to another page/complete a survey or a third option?
