I think, you have a notion that the earlier call-template above is
oddly numbered and the next one is an even numbered call. Solving this
in the strictest sense you wrote, is not possible unless we keep a
variable somewhere for counting, which can be incremented each time we
make a call to call-template.

If you are ready to use a Java extension (to keep a shared state),
almost any kind of counters can be implemented (please see an example
of this on my web page,
http://gandhimukul.tripod.com/xslt/extensions.html. - no 2).

But using an extension function to maintain shared state should be
used as a last resort, as it is against the spirits of functional
oriented and side effect free programming (which is one of the goals
of XSLT).

After knowing your input XML and the required output, though it might
be possible for us to comment if there could be a better way to solve
the problem.
