If your current node is the <fu/> element node, then the answer is "3".

All axes are traversed in a step in proximity order, so the preceding axis 
is traversed in reverse document order, so the closest one is the one with 

Note the different answer with "(preceding::bar)[1]/@id" which is "1" 
because the set of nodes in the parens is addressed by XSLT in document order.
