 Boost.DynamicBitset is a portable library that provides a set of bits.
 
-The set (cpp:dynamic_bitset[]) provides access to the value of individual bits
-via cpp:dynamic_bitset::operator\[\][] and provides all of the bitwise operators
-that one can apply to builtin integers, such as cpp:operator&[] and
-cpp:operator<<[]. The number of bits can change at runtime.
+The set (xref:reference:boost/dynamic_bitset.adoc#boost-dynamic_bitset[dynamic_bitset]) provides access to the value of individual bits

+xref:reference:boost/operator_lshift.adoc[operator<<]. The number of bits can change at runtime.
 
 `dynamic_bitset` is nearly identical to `std::bitset`. The difference is that
 the size of a `dynamic_bitset` (the number of bits) can change at runtime,
