Fair point. Current text reads

    | Expansion opportunities are divided into different priority levels:
    | within a level, all expansion opportunities are expanded or compressed
    | at the same priority, with space distributed in proportion to the
    | expansion opportunity’s 'font-size'.

Is that alright, or do you have suggestions to improve it? The point
I'm trying to get across is that if we say "between Latin letters"
and "between CJK letters" belong to the same priority level, the UA
is not allowed to treat them differently.
