This thread originated from postings to fop-users list and it deranged.... The
problem that
emerged was the following: position() seems to give results (which seem wrong)
according
to the presence or absence of xsl:strip-space, but maybe someone can exaplain.
I've used for these examples saxonb 8, fop 0.20.5, j2se 1.4.2, winxp pro.
One example, fortest3 produces the desired results. It contains
xsl:strip-space, and the xml
contains line-feeds which are removed by it. (There are no xsl:text elements).
The second example, fortest3b, doesn't. It does not contain xsl:strip-space,
nor the xml
contains line feeds. So what's its issue? Might this be a bug?

p.s. see code below (xml, xsl, 'output pdf') for both fortest3 and fortest3b.
-- contains <xsl:strip-space elements="*" /> --
-- filtered by "position() mod 2 =1" --

-- not filtered because I'd get an empty output, so just print all
for testing and what I find out? position() is always even, why escapes me ;) --
