Re: AW: [docbook-apps] ragged index with recent fop snapshots

Hi Markus,
Glad you found a workaround.  The purpose of the fo:inlines is as follows:

1.  The first one with keep-with-next.within-line="always" is intended to keep the 
text of the entry connected to the dot leader. If a line is long and has to break, it 
breaks by carrying the last word or words of the entry, plus dot leader, plus page 
number to the next line.  That prevents the dot leader from breaking to the next line 
by itself, leaving the text above it.  This is a typesetting nicety, not a necessity.

2.  The second one with keep-together.within-line="always" is intended to keep the dot 
leader connected to the page number. That prevents the page number from breaking to 
the next line by itself,  leaving the dot leader above it.

If removing them makes no difference in your output, it may be that FOP does not 
support such keeps for fo:inline.  The FOP compliance page isn't quite clear on that:
