question on docbook header formatting

[Jack]

Running khelpcenter, looking at the TOC produced by meinproc5, within a  
chapter, if a sect1 has several sect2s within it, there is no extra  
space between the sect1 title and the first sect2 title, nor between  
the sequential sect2 titles.  There IS a space between the last sect2  
and the following sect1.  However, there is no space between two  
sequential sect1 titles, if the first does not contain any sect2.  This  
looks odd to me, but I suppose it has been that way for a long time.   
Am I the only one who thinks this, and is there any reasonable way to  
change it?  Simply adding space before any sect1 title would add  
unwanted space between a chapter title and the first sect1 title, so I  
know it's not trivial to do.

Any thoughts or suggestions?
