[Xen-devel] what does "See 3B 23.2.1 Table 23-1" mean?

hi,all

when I read xen source code ,I find 

        switch ( vector )

        {

        case TRAP_debug:

            /*

             * Updates DR6 where debugger can peek (See 3B 23.2.1,

             * Table 23-1, "Exit Qualification for Debug Exceptions").

             */

            exit_qualification = __vmread(EXIT_QUALIFICATION);

            write_debugreg(6, exit_qualification | 0xffff0ff0);

            if ( !v->domain->debugger_attached || cpu_has_monitor_trap_flag )

                goto exit_and_crash;

            domain_pause_for_debugger();

            break;

what does  "See 3B 23.2.1 Table 23-1" mean?
