    I also agree that small capitals have a tertiary or quaternary differences,
    but it's not clear if they are a variant of lowercase when used as a font
    style for all letters, or of uppercase letters.

    So I bet they should have the same distinction as between lowercase and
    uppercase, so that case-insensitive collation (which ignores secondary
    differences) will work correctly even if tertiary and quaternary difference
    are kept to sort accents and other minor variants, probably by sorting small
    capitals between uppercase and lowercase letters at the same collation

    The simplest way to allow tailoring is to map small capitals as secondary
    differences between uppercase and lowercase letters, and let a tailoring
    remap them in one simple operation to quaternary level, where a 1-weight gap
    has been left in quaternary collation weights to allow such remapping
    without needing shifts of weights.
