[NTG-context] solution to suppressing header in ToC

[jbf]

Hi list,

I am offering the solution I found for myself for suppressing headers in 
a multipage Table of Contents, after trying a number of other 
unsuccessful approaches. My solution may be useful for others, but it 
may also be that, while it works, there may be even better solutions 
that someone wishes to offer.

The problem was that

\definehead
   [tochead]
   [title]
\starttochead[title={Contents}]
\setupheader[state=stop]
   \placecombinedlist[content]
\stoptochead

was giving me headers on the second and third pages of the ToC, and my 
publisher did not want those headers to appear, but did want page 
numbers still.

A successful solution is:

\starttochead[title={Contents}]
\setupheader[state=stop]
   \placecombinedlist[content]
\stoptochead

and then, after, the first full text page, to put:

\starttitle[title={Acknowledgments}]
\setupheader[state=empty]

If I had state=normal, it gave me a header on the first page of 
'Acknowledgements'. but state=empty gave me what I needed in this case.
