Call it (positive logic) AND or call it (negative logic) OR, or what ever you might want to call it. The only interesting thing is the truth table. And I know how it looks like if you speak of a (positive logic) AND or an (negative logic) OR.
Today when you, most often have 2 gates or less in a "string" it may be less important, but try to follow a 7 gate string where the gates are shown by 'type' rather than 'function' and you will get lost.

Unfortunately, by convention, gate functionality is almost always (I don't know of any opposite case) expressed based on positive logic.
Language??? I disagree on 'funtionality' but agree on "datasheet description"
