: 1. Is a ConTeXt layer accepted as a whole in commercial Acrobat, or is it visible as a heap of small objects? Or is it "only" better for more comfortable manipulation in ConTeXt? I don’t understand the question. A ConTeXt layer is not a PDF layer. All the objects are manipulatable in Acrobat Pro (or another PDF editor),

: there’s no grouping on the PDF level. If you need PDF layers, there are "viewer layers" in ConTeXt: \defineviewerlayer[Ebene] \setupviewerlayer[Ebene][ state=start, visible=no, title=Test, ]
\starttext
Text
\startviewerlayer[Ebene] {\bfa TOP SECRET} \stopviewerlayer
More Text
\stoptext
AFAIK completely undocumented, I found them at http://source.contextgarden.net/tex/context/base/mkiv/attr-lay.mkiv while tracking effects/properties (where these were implemented first).
While the example above works, I don’t get viewer layers in my current project, must investigate... And then, if the combination of ConTeXt layers and viewer layers works (\setlayer within \start/stopviewerlayer?).
You have to put the viewerlayer command within the the \setlayer argument. Wolfgang
