XSLT 1.0 -- grouping items from a list of items of variable length

From: jhendrich@----------.------

Hi,

I want to transform a list of items that can be of variable length into 
groups of 6 items each, with the last group possibly having less than 6.

For example, the source list might have 40 items.  I therefore would want to 
achieve 6 groups of 6 items plus a 7th group of 4 items.

Specifically, given a list of images, I want to create n pages with 6 images 
each.  

Question:  Is there a way to do this, or is this a limitation of XSLT?

For reference, you can see how I had originally intended to do this...except 
that it doesn't work due to needing to mismatch start and end tags.

Example source xml:

<Images>
   <Image>23.01.20 hrs __[0000033].bmp</Image>
   <Image>23.01.16 hrs __[0000034].bmp</Image>
   <Image>01.45.16 hrs __[0000035].bmp</Image>
   <Image>01.45.20 hrs __[0000039].bmp</Image>
   <Image>01.45.20 hrs __[0000043].bmp</Image>
   <Image>01.45.16 hrs __[0000044].bmp</Image>
   <Image>02.45.16 hrs __[0000053].bmp</Image>
   <Image>02.45.20 hrs __[0000063].bmp</Image>
   <Image>03.45.20 hrs __[0000072].bmp</Image>
   <Image>03.45.16 hrs __[0000077].bmp</Image>
   <Image>04.45.20 hrs __[0000044].bmp</Image>
   <Image>04.45.16 hrs __[0000045].bmp</Image>
   <Image>23.57.21 hrs __[0000005].jpeg</Image>
   <Image>18.34.27 hrs __[0000006].jpeg</Image>
   <Image>21.59.27 hrs __[0000006].jpeg</Image>
   <Image>22.57.21 hrs __[0000105].jpeg</Image>
</Images>

XSLT:

<xsl:template match="Images">

	<!-- insert a page break -->
	<p style="page-break-before: always;">

		<!-- display is 6-up per page -->
		<table class="n6up">
			<xsl:for-each select="Image">
				<xsl:if test="position() mod 6 = 0">
					</table>
					</p>
					<p style="page-break-before: always;">
						<table class="n6up">
				</xsl:if>
				<xsl:if test="position() mod 2 = 1">
					<tr>
						<td class="n6up">
							<xsl:element name="img">
								<xsl:attribute name="class"><xsl:value-of 
select="'nUpImage'"/></xsl:attribute>
								<xsl:attribute name="src"><xsl:value-of 
select="string(.)"/></xsl:attribute>
								<xsl:attribute name="alt"><xsl:value-of 
select="string(.)"/></xsl:attribute>
							</xsl:element>
						</td>
				</xsl:if>
				<xsl:if test="position() mod 2 = 0">
						<td class="n6up">
							<xsl:element name="img">
								<xsl:attribute name="class"><xsl:value-of 
select="'nUpImage'"/></xsl:attribute>
								<xsl:attribute name="src"><xsl:value-of 
select="string(.)"/></xsl:attribute>
								<xsl:attribute name="alt"><xsl:value-of 
select="string(.)"/></xsl:attribute>
							</xsl:element>
						</td>
					</tr>
				</xsl:if>
			</xsl:for-each>
		</table>
	</p>
</xsl:template>


Thanks.
Jon
