This expression evaluates to an unrepresentable object of type "<type>"

The Relevance engine requires a basic framework for an answer. Sometimes a statement can exist and be usable, but not be representable in the debugger context:

Q: Key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX" of registry
E: This expression evaluates to an unrepresentable object of type "registry key"

Even though this key exists, there is no operation indicated and the Relevance engine doesn't know what to produce. We need to be more specific:

Q: exists Key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX" of registry
A: True

Or perhaps we want to know about a value in the key:

Q: value "Version" of key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX" of 
registry
A: 4.09.00.0904
