oh yeah, i am a stupid guy. AXIS is the magic word!... Many thanks
for your detailed explanation below. I forgot my self-made rule when
dealing with XPATH:

"Dont use XPATH shorthands when it comes to problems" which leads
normally to question "What is your axis..." :-)
(my second best rule for XPATH is: try thinking in sets of nodes )

BTW: it is acommon fault in many documentations for beginners to
start with abbreviations of XPATH Expressions. I dont like them. In
XSLT you have to type a lot of things anyway. (ok i dont want to miss
them, but they just help you typing faster, not understanding faster,
but i guess thats common for all abbreviations :-)

thanks a lot.

kind regards,
janning
