Identifying SQL Server 2005 Enterprise Edition features in Use

Not sure what that question means. (Sounds like Dutch, "ben je klaar?") But if you're asking if I understand the problem, yes, I do. I think that such a script would be quite long and very tricky since most of the features are in the setup info, not in any particular instance. Not only that, but what would you scan? e.g. suppose you have an application that issues ad-hoc queries that use the SQL MERGE command, for example. No SQL script can find those unless that script can also read and understand the source program (VB? C#, C++? Java? JavaScript? PHP? etc).
