Which of them should be taken? Hmmmm. For such a system, I assume you'd have something like an \addfontshape command, since you don't want to specify all previous font shapes when supplying a new one (in the same way as \bfseries is applied without having to say \sffamily -- this is the whole point of orthogonal axes). [I guess it would have to be clever enough to realise that a definition like {u&lc,sc} doesn't make sense and decompose it to {sc} (with a warning).] So, the current shape is {n,u&lc,osf}. You want to get to {it,sc,osf}. I assume here that the \addfontshape{it,sc} command is actually a shorthand for \addfontshape{it}\addfontshape{sc} and you'd get \addfontshape{it} -> {it,u&lc,osf}, then \addfontshape{sc} -> {it,u&lc,osf} + warning If the arguments to \addfontshape command were reversed, you'd get the {n,sc,osf} + warning instead. How does this sound? Will
