Consider the case of implementing a COM object in C++ using ATL.

This ATL C++ class implements some COM interfaces, that are listed as base classes.

In addition, these COM interfaces should also be added as entries in the COM map, using the 
COM_INTERFACE_ENTRY
macro.

If the entry in the COM map is missing, you can get subtle bugs, as described in this blog post:

So, it's good to have Visual Assist X emits at least a warning in such cases.

Are you talking about having VA check existing code, or is this when you are writing / creating new code?

The current Code Inspection feature is based on Clang, and is checking C++ features, so is rather unlikely to pick up ATL specific points.
