I 100% agree with what you're saying. And that's why I'm arguing about this issue so much, don't take it personal.

In this case, "config" is one of the schemas in this catalog. I don't have a catalog named "config." My catalogs generally refer to individual database instances - e.g. my "dev" db, my "qa" db, my "uat" db. Each of those catalogs has their own unique "config" schema (the structures generally the same within the same release line, contents likely vary between dbs).
