Well, now it comes an attempt to give an authoritative confirmation.

Given the following sample:

    \nopdfcompression
        \setupinteraction[state=start]
    \placebookmarks[chapter,section,subsection]
        %[chapter,section,subsection]
    \starttext
    \startchapter[title=Chapter]
    Hi!
    \startsection[title=Section]
    I don't know
    \startsubsection[title=Subsection]
    Good point.
    \stopsubsection
    \stopsection
    \stopchapter
    \stoptext

If you compile it as it is, you may use a tex editor to search for
"Count -1" (that is, chapter has a hidden child and section has another
closed one).

If you remove the comment, those entries will read `/Count 1`, which
means that both chapter and section have a visible children.

All this comes for my understanding of table 153 of the PDF spec
(https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf#nameddest=G11.2095911).
“Count” is the last key entry from that page.

BTW, not being English my mother tongue, I cannot get what “immediate”
adds to the expression ”immediate children” in this context.

I mean, isn’t the distinction between children (since all children would
“immediate” in this context) and other (further) descendants?

Just in case it might help,

Palo
