I tried using both and it seems they just validate the same way. And also, their validation codes are the same. Are there any difference between phoneStrict and phoneLax at all? Or you can just use either?
validate-phoneStrict Please enter a valid phone number. For example (123) 456-7890 or 123-456-7890
validate-phoneLax Please enter a valid phone number. For example (123) 456-7890 or 123-456-7890
This question applies to both M1 and M2.
