Sorting like elements

["Steven L. Anderson" <steveo@xxxxxxx>]

I'm just getting into DSSSL and I'm confused about sorting.  What I'd
really like to do is create a topological sort, but I don't have a
clue even where to start.

If my document has the following

   <para id="procedure1a">
         A procedure that needs a warning before it.
   </para>
. . . 
   <para before="procedure1a" id="warning3">
         Don't eat the mercury!						
   </para>

Is there anyway to get jade to sort the paragraphs before output so
that the warning goes before the procedure?  Is it still possible if
the elements have different parents?

Any tips would be appreciated.
