(EX allows > preceding break only after hard line break or ZWSP; BA also allows a > preceding break after spaces (SP) or FFFC). I thought I might clarify what I meant by "strongly blocks" and "less strongly blocks" here: it is what I stated in the parenthetical comment: a break is allowed before EX in very limited cases (i.e., between very few character-class sequence pairs), while a break before BA is just slightly less restrictive. It does *not* mean that if break opportunities were weighted that one would be given more break priority than the other. For instance, character-pair sequences with line breaking class <AL EX> and <AL BA>, the bond between the two characters is equally sticky in each case. Peter
