Thanks for the reply. However it doesn't help me resolve my problem.
I only write xsl once in a blue moon and I have to reread Michael's book
every time. Unfortunately I don't have time to do that now. Can you tell
me how I can compare the previous value in a for-each loop with the
current value if the xsl:variable approach doesn't work. I tried using
preceding but it didn't seem to work.
Any help would be greatly appreciated,
Regards
Jan

FOP 0.20.2 implements an old draft of the XSLFO 1.0 standard. FOP
0.94 implements a subset of the standard. Some important details
have changed, you'll have to rework your XSLT. Furthermore, FOP
0.94 validates the FO much more strictly by default.

This should never have worked, because you can't reassign a variable
in XSLT.

This is the expected outcome. Again, you probably have to rewrite your
XSLT rather thoroughly.
