[xsl] position() question

[Garvin Riensche <g.riensche@xxxxxxx>]

Hello,

I just came across an example where I am wondering about the value that 
is calculated by position().

Please have a look at:

In my enviromnent (saxon 8) I dont get the desired result as in the 
example. My value of position() is 2,4,6,...,22 instead of 1,2,3,...,11. 
So every item gets the color yellow. But I dont know why, because the 
iteration goes over the 11 "item" elements. Where do the other elements 
come from that are counted?

regards,
Garvin
