Hi Rob,

You can certainly bind two selects/select1s to the same node, but when 
you select items in a select/select1, it will replace the values 
underneath it.  The only way you could mix and mingle them are if both 
selects had the same items and you use ctrl+<click> when selecting items 
(assuming your process uses a html:select type of control) but then 
there isn't much reason to have both.  You could always try to manage it 
yourself with binding the two selects to different nodes and then 
handling the xforms-select and xforms-deselect events and 
inserting/deleting the nodes under the 'real' target node yourself.
