MVC Conditional Vallidation RequiredIf
I am using a custom validation, it works great for one value, however I need to check for Multiple values, for example:
  

>  [RequiredIf( "Country", "Canada", "Postal Code is Required") ]   
> [RequiredIf("Country", "United States", "Zip Code is Required")]   
> public string PostalCode { get; set; }

I get Duplicate 'RequiredIf' attribute!
Thanks in advance.
