Hi,
Let me clarify my question more...
I need to attach some value to a chapter in that key. That custom prefix +
the value in the key is ment to be in the header or a footer as a matter of
fact. The case can apply to both headers and footers.
I tried:
\chapter[title={A sample title}][custom_random={custom_value}]
\setupheadertexts[{Prefix: \structureuservariable{custom_random}}]
...
\stopchapter
I tried this code when trying to figure out the mechanism. The prefix
string in placed in the header, but hte custom value of the attached key is
not expanded..
Evey page will contain just one section started by a \startchapter and
\stop chapter. I would like to put this custom attached value in the right
slot in the document header.

I hope that htis time around htigs are more clear.
