In the last post, we looked at the complementary clause, and saw how powerful it can be; we also looked at the limits of that power. Many architects know of that clause, and I have occasionally heard it cited, something like this: "I don't care if there is no specification for it; it's on the drawings, and you have to provide it!" In the same conversation, it wouldn't be unusual to hear, "No, I don't know how you're going to do it - that's means and methods!"
