Yah, I can currently implement previous:: with no problem,
except for the fact it's a "reverse axis", and thus I don't
actually maintain the correct order.  (It currently results 
elements in document-order, as opposed to reverse-document-order,
as specified.)  I simply walk from [root] to the current
context.  Reversing them should be simple enough, so I'm
not clamoring for a doubly-linked-list.
