Hi,

Is it possible to have TeX markup executed in the text fields for
\setupinteraction?
I would like to do something like:

\definemarking[xyz]
\marking[xyz]{Hello}
\setupinteraction[state=start]
\setupinteraction[title={\getmarking[xyz][current]}]
\setupinteraction[author={\getmarking[xyz][current]}]
\starttext
xyz=\getmarking[xyz][current]
\stoptext

But my generated PDF has literally "\getmarking[xyz][current]}" for
the title and author.
