Answering myself: I should use:
\ctxlua{lpdf.addtonames("EmbeddedFiles", lpdf.reference(22)) \ctxlua{lpdf.addtocatalog("PageMode", lpdf.constant("UseOutlines"))}
(Apparently I can't do that directly with \pdfbackendsetname/catalog, the second argument is taken as a string.) I hope that's the correct answer and not a hack.
There are mechanisms for embedding files, like backends.codeinjections.embedfile(filename) However, a nametree is not constructed (as with forms these are not mandate, but with forms they are better be there due to initialization). Anyhow, I added this now: local function flushembeddedfiles() if next(filestreams) then local e = pdfarray() for name, reference in next, filestreams do if reference then e[#e+1] = pdfstring(name) e[#e+1] = reference -- already a reference else -- we can issue a message end end lpdf.addtonames("EmbeddedFiles",pdfreference(pdfflushobject(pdfdictionary{ Names = e }))) end end lpdf.registerdocumentfinalizer(flushembeddedfiles,"embeddedfiles") As with most of these things, it's best to use the interface and not push things in the file directly as it might render existing functionality ineffective. Examples are color related resources. In a similar fashion Pagemode is not to be set directly. There is \setupinteractionscreen for this (with a low level lua setupcanvas variant). As some of the parameters influence each other they are dealt with at another moment. Also, some of the parameters are ignored or overloaded when a chosen pdf/x standard has rules that concern them.
