At least three readings come to mind: (1) a subset $D$ of $B$ with $b\in B\ \&\ d\in D\ \&\ b<d$ implying $b\in D$; (2) a subset $D$ of $\omega$ with $d\in D$ implying existence of $b\in B$ with $d\leqslant b$; or (3) same as (2) and in addition $n\in\omega\ \&\ n<d\ \&\ d\in D$ implying $n\in D$. | |
