Override a resource from standard assembly in ASP.NET

I want to override a string from a System.ComponentModel.DataAnnotations for an ASP.NET project. Do I need to make a satellite assembly, messing with custom build tasks, al.exe etc.? Even if yes, I couldn't find how to convert .resx to .resources to feed it to al.exe. And if no, where to put the .resx. and how to name it?

UPD: To make it clear: I wanted to use a custom resource string instead of one from the default resource from the assembly. I didn't want to make changes in the every place that uses that string. After all, the resources exist just for overriding them.

While this is strange, especially for people familiar with open source localization technologies, one cannot build a satellite assembly for any system assembly or even a 3rd-party signed one:

If your main assembly uses strong naming, satellite assemblies must be signed with the same private key as the main assembly. If the public/private key pair does not match between the main and satellite assemblies, your resources will not be loaded.

Whether the same is possible automatically, but without a satellite assembly, is unknown, though I doubt that.
