please see below, near 'group-starting-with'

I have a MS spreadsheet xml that I will be transforming into an html table.
I need to use group-starting-with to group multiple rows into one
based on empty cells in the first column.

ex. If I have

Col A, Col b, Col c
1a, 1b, 1c
    ,  2b, 2c
    ,      ,3c
4a,4b,4c
     ,    ,5c

I will eventually create a html table with two rows and three columns.
For now I am trying to just get grouping to work, but I got stuck.
Just when I thought I had for-each-group figured out I get stumped again.
Can you get me going in the right direction?

My xslt
---------------------------------------------------------------------
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">
<xsl:output encoding="iso-8859-1" method="xml" indent="yes"/>

<xsl:template match="ss:Workbook">
<body>
      <xsl:apply-templates select="ss:Worksheet[1]/ss:Table"/>
</body>
</xsl:template>

<xsl:template match="ss:Table">
	<xsl:for-each select="ss:Row">
		<xsl:if test="ss:Cell[1][not(@ss:Index)]"><data>grouping row</data></xsl:if>
	</xsl:for-each>
<data>show them grouped now</data>
	<xsl:for-each-group select="ss:Row"
group-starting-with="ss:Cell[1][not(@ss:Index)]">

This is a pattern. You have to specify at which element the grouping should start, just as you'd specify a template's match: group-starting-with="ss:Row[not(ss:Cell[1]/@ss:Index)]">

		<group>
		<xsl:copy-of select="current-group()"/>
		</group>
	</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
---------------------------------------------------------------------
End My xslt

For this example, I want output that looks something like the following.
It doesn't have to be exact, but if I can get two groups with the
implied cell data, then I can probably go from there, I hope.

A complete stylesheet with @Index-Cell expansion may look like:
