Hi Bart,
I've done some playing with markers also and gotten them to work pretty well. One of the things I've noticed is that FOP complains mightily about both "fo:marker must be an initial child"" and "marker-class-name' must be unique for same parent."but, they are recoverable errors and can be ignored.
Here's an XML and XSL to demonstrate the capabilities. Notice that I place a marker at the beginning and end of each marked block (That's strictly illegal! But it works) I also have placed an "x" in the illegal marker contents so you can see the illegal retrieval. I do that so that the functions first-including-carryover and last-ending-within-page will work. Arved did a great job of implementing markers, you just have to break the rules for now (and be prepared to unbreak the rules when FOP has a correct implementation)
fop -xsl dictionary.xsl -xml dictionary.xml -pdf dictionary.pdf

does fop support markers? i'm having trouble getting them to work.
my input looks like ... <fo:flow> <fo:block> <fo:block> <fo:marker marker-class-name="chap">chapter one</fo:marker> ... </fo:block> </fo:block> <fo:block> <fo:block> <fo:marker marker-class-name="chap">chapter two</fo:marker> ...
note that the markers share a common great-grandparent.
the error message i get from any fop-0.20.[23] is:
[ERROR]: fo:marker must be an initial child,and 'marker-class-name' must be unique for same parent.
i'm following all the rules, i think, but no joy.
sounds like a simple misconception on my part but i'm stumped.
