There is a description. Here's what the docs say:

Member Typesdefs

dynamic_bitset::reference

A proxy class that acts as a reference to a single bit. It contains an
assignment operator, a conversion to bool, an operator~, and a member
function flip. It exists only as a helper class for dynamic_bitset's
operator[]. That is, it supports the expressions x = b[i], b[i] = x, b[i]
= b[j], x = ~b[i], and b[i].flip(). (Where b is a dynamic_bitset and x is
a bool.)
