I think you're on the right track with the position function, although I
didn't see that code in the stylesheet you included with your message.

Take a look at page 367 in Michael Kay's XSLT book.  The very last entry in
the Examples table shows this method of determining whether a node's
position is even:

item[position() mod 2 = 0]

Use this in an xsl:when test something like this:

  <xsl:when test="Summary[position() mod 2 = 0]>
    <xsl:call-template name="bgcolorgrey"/>
    <xsl:call-template name="bgcolorwhite"/>

You can then create two named templates to create the table rows, one
implementing a gray background and the other implementing a white

I thought about a simpler way to do this, which would be to simply do the
test and set a variable value to the desired color, then use the variable
for the 'bgcolor' attribute of the <tr> tag.  I'm not sure if that would
work, though.  I'd be concerned if the variable would stay in scope after
you exit the xsl:choose, and I'm also not sure if it would be recreated for
each node processed in the xsl:for-each (although I think it would).
Perhaps someone more experienced than I am can comment on that.

Hope that helps!
