Travis Brown and Gary Sidhu from Qwest Communications and I have written a whitepaper on the benefits of using the Visual Studio DSL toolkit for a software system that activates IP VPNs for a telecommunications network service provider.  The whitepaper makes use of the TMForum's Shared Information and Data (SID) model and the DSL is based on the RFC2547bis standard.
