Re: System.ComponentModel.DataAnnotations/EmailAddressAttribute.cs 

Currently allows the following (invalid) email addresses:
[1] email@example
[2] email@example.web
[3] email@111.222.333.44444

[1] If a plain address (i.e. just a the username (no @) is invalid) then surely email@hostname should be okay?
(Yes, I know that reasoning is stretching, but I do think both or neither should be allowed)

[2] Obviously the .web tld could exist in the future

[3] 111.222.333.44444 as a domain name certainly shouldn't be allowed, unless the RFCs have been changed to allow numeric TLDs? 

I'm not how this compares to Microsoft's EmailAddressAttribute as I don't have access to that currently, but if .NET fails in the same manner, I think MONO should be bug compatible.

Best Regards,
