producing month list in xslt 2.0

Hello

I'd like to be able to display the next 12 months for use in a calendar
application.

What I have so far:

<xsl:param name="thisMonth"  select="xs:date(format-date(xs:date($m),
'[Y]-[M01]-01'))"/>

<xsl:param name="lastMonth"  select="$thisMonth -
xdt:yearMonthDuration('P1M')"/>

<xsl:param name="nextMonth"  select="$thisMonth +
xdt:yearMonthDuration('P1M')"/>

Is there a way to loop through the next or previous 12 months (wrt the
current focus month, $thisMonth) using the built-in date time functions,
or am I required to call a counter template to loop from 1 to 12?

Thanks for any guidance, David
