[boost] Copy Constructible Concept

Why are requirements about the address operator (&) included in the 
CopyConstructible concept at 
http://www.boost.org/libs/utility/CopyConstructible.html?  This strikes me 
as an error of taxonomy, as there is no essential reason why the two 
issues belong together.  There are many algorithms that require one to be 
able to copy values, but don't care about taking addresses, and we have 
boost::addressof() anyway.
