1. I want to be able to display error messages for the specific culture that is being used.
2. I have a Model that is using DataAnnotations and I also have several resource (resx) files with the same error message, but in a different language. 
3. I know that I need to somehow link from the data annotation to the Id of the message in my resource file, but am unsure of the syntax on how to accomplish that.

Say for instance I have the below DataAnnotation file. I need to link the ErrorMessage text to the specific key in my resource file. What would it need to look like by implementing step 3?

In additon, for fields like zip codes or telephone numbers (where it's a different regular expression, would I have to take out the message from the model and apply it to each view that is using the model?

Or, is there a way to specify which regular expression I can use in the model?

using System.ComponentModel.DataAnnotations;
using DataAnnotationsExtensions;
