> fop2.0 crashes if docbook <note> is last inside a <listitem> or a <step>. No 
> bug in fop1.1
> 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!
