[NTG-context] \setupheadertexts for chapters with different authors

[Henning Hraban Ramm]

Hi Julian,

you’re right, the example didn’t do what you wanted, and it didn’t 
intend to.

Using \getmarking you can get a section title (or another “mark”), you 
can’t combine it with the variable commands, and you don’t need it for 
your case.

https://wiki.contextgarden.net/Command/getmarking isn’t really helpful 
since there’s no example with section titles, but it shows you can also 
get previous or next “marks”.

BTW, I can’t remember when you need \structurevariable vs. 
\namedstructurevariable...
