In the visual adjustments section, the check for display modifiability is before the check whether a publication is fixed layout. This means that if someone claims their fixed layout is display modifiable, that overrides what would otherwise be said for it being a fixed layout.

Is that what's intended here? The appearance of fixed layout publications typically can't be modified, even if the markup theoretically allows them to be. I'm assuming that's why we test for fixed layouts and output the statement that the display cannot be modified in those cases.

Should these checks be reversed so that fixed layouts always result in the appearance not being modifiable?
