Re: RE: sequence numbering.

<xsl:number> gives you the position of the element in the source tree, not
in the sorted sequence. To get the number in the sorted sequence, do a
two-phase transformation: create a temporary tree that contains the sorted
products, then process this (using xx:node-set()) to add the numbers. To get
the number for a product among all the products of the same colour, use
<xsl:number count="product[color=$this_color]"/>
