Solution 1

You don't put that in the IDL file. Take a look at this MSDN example that shows how to use STL types with ATL:

Solution 2

In short, you can't. You can use STL and such to implement COM exposed methods but the methods themselves can only accept certain types as parameters. See here[^] for a list and details. COM is language neutral so it wouldn't make sense to export C++ specific types.
