Confusing level change message, why?

Confusing level change message, why?

[Rik Kabel]

[-- Attachment #1.1: Type: text/plain, Size: 1438 bytes --]

The example below is taken from the wiki article "Titles 
<http://wiki.contextgarden.net/Titles>," with pdf bookmark apparatus 
prepended and a second chapter added to the bodymatter.

In the log, this produces the lines:

    backend         > bookmarks > confusing level change at level 3
    around '1 body'
    backend         > bookmarks > confusing level change at level 3
    around 'A appendix'
    backend         > bookmarks > confusing level change at level 3
    around 'back'

That is, one message for each *matter change.

What is the meaning of the message, and how can it be removed (short of 
disabling pdf bookmarks)?

    \setupinteraction[state=start]
    \placebookmarks[chapter, section, subsection, subsubsection]
                    [chapter,section]
    \setupsectionblock[frontpart][page=]
    \setupsectionblock[bodypart] [page=]
    \setupsectionblock[backpart] [page=]
    \setupsectionblock[appendix] [page=]
    \definepagebreak[firstpagebreak][yes,header,footer,right]
    \setuphead[chapter][page=firstpagebreak]
    \setuppagenumbering[alternative=doublesided]
    \starttext
    \startfrontmatter
    \chapter{front}
    \stopfrontmatter
    \startbodymatter
    \chapter{body}
    \chapter{body}
    \stopbodymatter
    \startappendices
    \chapter{appendix}
    \stopappendices
    \startbackmatter
    \chapter{back}
    \stopbackmatter
    \stoptext

Hi Rik,

if you disable bookmarks (by commenting
"\setupinteraction[state=start]"), you won’t get the message.

But I wonder what is the problem besides the log message. From your
sample, I get a PDF document with all the expected content.

What I am missing from your explanation? Or why are these log messages
so relevant if you get the intended output?

Pablo

Indeed, Pablo, there is no visible defect in the document.

I wonder if the message should cause concern because I do not know if 
there is some other issue that it reflects, perhaps something that is 
not visible in the viewed document, but that might impede PDF standards 
compliance.

If there is no fault or typesetting problem indicated by the message, I 
wonder why it is reported.

Again, if there is no problem, I can add it to my log filtering 
routines, but I want to see it if there is something I should do to 
eliminate it.

it's just part of the check .. if you use for instance \section{foo} 
instead of \startsecction there is some guesswork
