Sorting in two passes will need much additional memory (O(N)) and therefore is not
practical for long node-sets.

Another approach is to have a sequence of (4 - 5) xsl:sort elements in proper order
of precedence, each specifying the numeric equivalent of a part of the date.

In this case you'll have to reference a lookup variable containing the month names
in their chronological order and to use the position of a specific month as a sort

A third and the most natural approach is to use a generic template for a generic
sort operation. You'll just pass to this generic template a template reference
implementing the "greater than" relation for your format of dates.

The same generic sort template can be used for sorting nodesets, the type of whose
nodes may be different (and not known in advance) at each instantiation of the
