DocBook chunking starting with second subsection

Hello,

I am generating chunked HTML output from a DocBook 5 XML document but 
the start points of the chunks seem inconsistent: sometimes a new chunk 
starts at the second subsection of a second, sometimes it includes all 
the subsections of a section. For the attached file I set the 
chunk.section.depth parameter to 5 and the whole Section 1 (with 
subsections 1.1 and 1.2) is included in one chunk but Section 2 is split 
in two chunks: Section 2.1 and Section 2.2. Is Section 1.2 not supposed 
to go to a separate chunk too? Does anyone know how I can make the 
splitting consistent?


Thank you,
Sorin
