RE: Simple lookup in XSLT2

As Michael correctly stated, there were a bunch of errors in the small
fragment I wrote (lack of QA in my e-mail's - not the actual code) and
yes, I was of course using XSLT 1.1 (obviouly with Saxon 6.5.5)

However even with typecasting it did not work with XSLT2 (using Saxon
8.8). I have not tried out Davids proposal yet, but that might be a
solution. At least there was not a major conceptual change betwwen XSLT1
and XSLT2 behaviour I had missed.

Thanks guys, I just have to keep digging  until I find the culprit.

Regards,

Jens
