The discussion went on about my silly PS. So I am reposting the  
original question/problem.
The method in the wiki (http://wiki.contextgarden.net/ 
Document_Titles) does not work for me, but maybe it is the order in  
which you have to do things?
Try this:
\unprotect
\definesystemvariable {title}
\definemarking[documenttitle]
\definemarking[documentauthor]
\definemarking[documentdate]
\def\setuptitle
 {\dodoubleempty\dosetuptitle}
\def\dosetuptitle[#1][#2]%
 {\ifsecondargument
    \def\dodosetuptitle##1{\getparameters[\??title##1][#2]}%
    \processcommalist[#1]\dodosetuptitle
  \else
    \getparameters[\??title][#1]%
  \fi}
\def\placetitle
 {\dosingleempty\doplacetitle}
\def\doplacetitle[#1]%
 {\iffirstargument
    \getparameters[\??title][#1]%
  \fi
  \def\dodoplacetitle##1%
    {\marking[document##1]{\getvalue{\??title##1}}%
     \blank[\getvalue{\??title##1\c!spacebefore}]%
     \doattributes{\??dt##1}\c!style\c!color\getvalue{\??title##1}%
     \blank[\getvalue{\??title##1\c!spaceafter}]}%
  \@@titlebefore
  \processcommalist[\c!title,\c!author,\c!date]\dodoplacetitle
  \@@titleafter}
\setuptitle
 [\c!title]
 [\c!style=\tfd,
  \c!color=,
  \c!spacebefore={\v!force,2*\v!big},
  \c!spaceafter={3*\v!medium}]
\setuptitle
 [\c!author,\c!date]
 [\c!style=\tfa,
  \c!color=,
  \c!spacebefore={2*\v!medium},
  \c!spaceafter={3*\v!medium}]
\setuptitle
 [\c!before={\startalignment[\v!middle]},
  \c!after={\stopalignment},
  \c!title=,
  \c!author=,
  \c!date=\currentdate]
\protect
\setuptitle
 [title={Title to be determined},
  author={G.C.Th.~Wierda, M.Sc., MBA\footnote{IT Lead Architect,  
APG, http://www.apg.nl/}},
  date={July 2009}]
\setupheadertexts[{\getmarking[documenttitle]}] 
[{\getmarking[documentauthor]}]
\starttext
\placetitle
...
\stoptext
