Of course simple way works ok. Below I described why \getmarking may couse
suprises.

Suprisingly clever way has no results -- headers are just EMPTYon every page
/ every chapter. The same with prettier way (with \doiftext clausule).
Probably there is my mistake, I will come back to it.
While studying this codes I've come across two not obvious things. Let's
look at this (silly) document
\setupheadertexts[]
\setupheadertexts[chapter][section]
\starttext
\chapter{Chapter One}
Short introduction of \getmarking[chapter]
\section{Section in first chapter}
Body of \getmarking[section]
\chapter{Chapter Two}
\dorecurse{50}{Quite long introduction of \getmarking[chapter], which needs
at least one page. }
\section{Section in second one}
Body of {\bf\getmarking[section]}
\stoptext
The first is that \getmarking[whatever] used in bodytex and in header expand
to something different.
I can imagine that user has \in, \at, \about etc. instead, so that is not a
real problem. It puzzles me, however!
Another thing is that the header of the second page (begining of the SECOND
chapter) of this document contains a section mark
of the FIRST, already ended chapter. The same problem appear with plain
\mark primitive which is global. That is why I had to use additional
commands to reset marks. Is there any reasons for that that new part of
document (chapter, section) desn't reset marks of lower level parts?
... I've just noticed that the ConTeXt I use is a bit archaic. I will try to
do some upgrade and come back to the problem with fresh soft and mind.
