Is there such a thing as a “content/data only project” in visual studio

Question

I have a bunch of ancillary XML and XSLT files that I want to edit and manage in visual studio.

The files do not logically belong under any code project in my solution

Answer 1

This answer is just a convenient consolidation of the answers above given by Chris Fewtrell and Kenny Evitt, along with the slight modification in my comments above, and a bit more detail on what the declaration of the content items should/could look like:

    
        Debug
        AnyCPU
        {541463A7-7CFA-4F62-B839-6367178B16BD}
    
    
        x64
        ..\builds\$(Configuration)\
        ..\builds\$(Configuration)\Intermediate\YourProjectName\
    
    
        
        
        
          targetSubdirInOutputDir\app.log.basic.config
        
        
          yetAnotherFile.config
        
        ... more files ...
    
    
        
    
    
        
    
    
    

Note that this always copies all the "content" files to the output directory - the options "Copy If Newer", "Copy Always" and "Do Not Copy", as presented in the visual studio GUI ( appears as, for example, PreserveNewest in the .csproj file) are ignored.
