<xsl:key name="p" match="*">
<xsl:number level="any" count="*" from="/"/>
</xsl:key>
This creates a key of elements-by-position, so given a number it will
return the element at that position.
<xsl:variable name="posn">
<xsl:number level="any" count="*" from="/"/>
</xsl:variable>
This gets the position of the context node. (this could do with an
as="xs:integer")
<xsl:variable name="val" select="document($src)/key('p', $posn)"/>
This gets the value of the of the element at that position in document($src)
