At work today, we threw together this attempt:

xquery version "1.0";
declare option saxon:output             "omit-xml-declaration=yes";
declare variable $x := 99;

string-join(
    for $b in (128,64,32,16,8,4,2,1)
    let $xm := $x mod ($b*2)
    return
        if ( $xm >= $b ) then "1" else "0"
, "")

Do you have a better way?
