Hi Marc

Yes, it's a well-known topic. Strictly speaking, FOP behaves according
to the spec and XEP does not. That has been verified with the XSL
working group. The problem is that the effects may not match user
expectations which is why many FO implementations have chosen to reset
indents over the so-called reference area boundary rather than to adhere
to the specification.

If you want to learn about the details, I wrote a report on the topic
here: http://wiki.apache.org/xmlgraphics-fop/IndentInheritance

Long story short: you can tell FOP to "misbehave" and also reset the
indents. Check out [1] and look for "break-indent-inheritance". Or if
you configure FOP from Java code, look at [2] and look for
"setBreakIndentInheritanceOnReferenceAreaBoundary".
