As the case may be
The actual number of flannels you may have from time to time, which may be one or more flannels, or indeed no flannels whatsoever, as the case may be. That's as may be, as the case may be, as it were, but there is a theory, articulated by the learned drafters of AIFMD, among others, that / is a synonym for as the case may be.
