As far as I am aware, you can use the <tag> rule anywhere, so it sholud be 
possible to add it to your top-level project, a sub-project, or a specific 
target. You can even create your own name generator :).

Is creating a <tag> rule/name generator in the docs? If not, it should be. 
Volodya?

Use INCLUDES instead :). (Note the "S" on the end). <include> should get 
mapped by the

flags msvc.compile INCLUDES : <include> ; # or something like this

which are added to the RSP files. Check the RSP files. Try deleting the RSP 
files and trying again (currently, if a build fails, RSP files aren't 
correctly regenerated if you change project settings).

Also, is this the requirements or usage-requirements version of <include>..?
