> This works in fop1.1 and it is good docbook syntax and should not be a problem.
> A workaround, that also shows the problem, is to insert an empty <para> between </note> and </listitem), or directly in the .fo file, insert an extra <fo:block></fo.block>.
> We are now forced to use this workaround in the building scripts - not nice!
