I think the documentation is incorrect.
Could you check if this has been fixed in 1.34?
-Thorsten
The code below almost allows the transfer functions to work as shown in 
the current documentation, unfortunately 
'reversible_ptr_container::c_private()' is protected and stopping the 
lines 'from.c_private(). ...' from compiling. If c_private is made 
public then the transfer functions work correctly, possibly there's a 
further work-around?

Here's the code for 1.34:
template< class PtrSeqAdapter >
         void transfer( iterator before,
                        BOOST_DEDUCED_TYPENAME PtrSeqAdapter::iterator 
first,
                        BOOST_DEDUCED_TYPENAME PtrSeqAdapter::iterator 
last,
                        PtrSeqAdapter& from ) // strong
         {
             BOOST_ASSERT( (void*)&from != (void*)this );
             if( from.empty() )
                 return;
             this->c_private().
                 insert( before.base(),
                         first.base(), last.base() ); // strong
             from.c_private().erase( first.base(),
                                     last.base() );   // nothrow
         }
template< class PtrSeqAdapter >
         void transfer( iterator before,
                        BOOST_DEDUCED_TYPENAME PtrSeqAdapter::iterator 
object,
                        PtrSeqAdapter& from ) // strong
         {
             BOOST_ASSERT( (void*)&from != (void*)this );
             if( from.empty() )
                 return;
             this->c_private().
                 insert( before.base(),
                         *object.base() );                 // strong
             from.c_private().erase( object.base() );      // nothrow
         }
template< class PtrSeqAdapter >
         void transfer( iterator before, PtrSeqAdapter& from ) // strong
         {
             BOOST_ASSERT( (void*)&from != (void*)this );
             if( from.empty() )
                 return;
             this->c_private().
                 insert( before.base(),
                         from.begin().base(), from.end().base() ); // strong
             from.c_private().clear();                             // 
nothrow
         }
