[NTG-context] headings in line numbering

[Pablo Rodriguez]

Dear list,

I have the following sample:

  \setuppapersize[A6]
  \definelinenote[otherlinenote]
  \setupnote[otherlinenote]
    [compress=yes]
  \startsetups[line:notes]
    \setupinterlinespace[line=2.9ex]
  \stopsetups
  \setupnote[linenote]
    [paragraph=yes, compress=yes, compressmethod=separator]%
  \setupnotation[linenote][alternative=serried, width=broad]
  \starttext
  \startlinenumbering
  \dorecurse{3}{\subject{Heading\linenote{title}}
  \dorecurse{2}{text\linenote{some text}\linenote{another text}\par}}
  \stoplinenumbering
  \stoptext

How can I get headings added to the line numbers?

Many thanks for your help,

Pablo
