I didn't mention it, but I do write architecture diagrams which have input.

    data Version = Current | Future

    generate :: Version -> Diagram

Implementation uses a few if/else expressions. Really simple.

The final points of the post was that we should be able to generate architecture diagrams from other code. Parsing a service descriptor, generating them from tests, etc. You DO need a programming language.

Fair point, and an interesting distinction, I think. Diagramming from code vs. diagramming with code...
