You are correct sir! As I said in a post several weeks ago, PCS is not a rendered space so "Rendering Intent" has no meaning with regard to an input profile. The term "Render" applies to the transformation of an image stored in a color space not meant for viewing (like PCS) to a color space (device space) that *is* meant for viewing. It is by design that PCS allows for different "intents" in this rendering process.
