Or not.  It actually restricts numbers to 0,10-29,100-255, which doesn't 
help much.

Try this instead:

          <simpleType>
             <restriction base="string">
               <pattern value=
"((0|1[0-9]{0,2}|2([0-4][0-9]?|5[0-5]?|[6-9])?|[3-9][0-9]?)\.){3}(0|1[0-9]{0,2}|2([0-4][0-9]?|5[0-5]?|[6-9])?|[3-9][0-9]?)"
               />
             </restriction>
           </simpleType>
