There are 6 <r> elements.  Of those 6 elements the first child of 5 of them
is a <co> element, the other one starts with a <ca> element.  Since "ca" is
alphabetically before "co" I expect the <r> element with the <ca> element to
be the first <r> element listed. We can see that is not the case.

Within this <r> element there are 9 <r_t> elements.  The first child of each of
those <r_t> elements is a <co> element.  Since a <co> element is the first child
of each of these <r_t> elements I expect the <r_t> elements to be sorted by the
contents of the <co> element.  Unfortunately it seems alphabetical sorting has
been completely ignored here because <r_t> elements have not been sorted by the
contents of their <co> elements.  In fact the <r_t> element which I expected to
be alphabetically first actually appeared last.
