Many thanks for your reply, Wolfgang.
Now I have the minimal sample:
\startbuffer[demo]
author
text
\stopbuffer
\starttext
\startxmlsetups xml:initialize
\xmlsetsetup{#1}{doc}{xml:*}
\xmlsetsetup{\xmldocument}

\startxmlsetups xml:title:author
\xmlflush{#1}
\stopxmlsetups
\setupinteraction[state=start]
\xmlprocessbuffer{main}{demo}{}
\stoptext
With \setupmetadata it breaks compilation.
I know it is not the most elegant code, but in my real environment
xml:title:author outputs text.

Sorry for not having answered before, Wolfgang.
I’m afraid I don’t get how \ifcase is deployed with as conditional
(being \ifcase used to give numbers for weekdays or months).
The \ifcase command is the TeX version of a switch statement from other
programming languages.
The first case in \ifcase checks against zero which is shorter than
writing "\ifnum ... = 0".
The semicolon is also mysterious to me, I don’t know what it does there
in plain language.
The semicolon is a undocumented extension (I noticed it in the
definition of \page[quadruple]) of \numexpr in Luametatex for the
modulus operator.
Sorry, I know it has to be simple, but the syntax is too cryptic for me.
Could you write the first line in plain language?
Look at the second example of the Lua code in the example below for each
command (the first example is your version), the third example is just a
condensed version of example 2.
Sorry for asking that. I’m afraid this would be the only way I could get
what \ifcase is doing there.
As was mentioned above I used it as a check when the remainder was 0.

even if we would use \setupmetadata we'd still have \setupinteraction

[NTG-context] How can I do this?
Dear List,
I need a tip how to do this:
In the command \definepapersize[Mybook] the height should be not 24 cm, but a
little bit longer. My Problem is, as you can see on the PDF, that there are
troubles with the Gray Background. The Gray Background should begin with :
Mitunter. . I think it should be the topoffset, and the bottomoffset, but how
many .\bodyfontsize should I try?
Many thanks

There’s also \settaggedmetadata; I actually didn’t know \setupmetadata.
Both are missing in the wiki yet.
Also https://wiki.contextgarden.net/Command/setupinteraction doesn’t
talk about metadata. Sigh.
AFAIK the metadata from \setupinteraction is used for everything, as
long as you don’t overwrite it elsewhere.
