  I didn't look at this in details, but what you say here is not the
same as the expression your wrote above.  The expression select first
elements descendant of a:data whose @a:span has some specific value. 
Then it filters out the elements whose one child has the same value for
@a:span.

  Let say you have in $e the following two elements:

    <elem a:span="ref1"/>
    <elem a:span="ref2">
       <elem a:span="ref2"/>
    </elem>
    <elem a:span="ref3">
       <elem a:span="..."/>
    </elem>

  The last filter will then filter out the second element in this
sequence.
