pointed domain
     
         In most formulations of {domain theory}, a {domain}
        is defined to have a {bottom} element and {algebraic} {CPO}s
        without bottoms are called "{predomains}".  David Schmidt's
        domains do not have this requirement and he calls a domain
        with a bottom "pointed".
