Again Watermarks:
Apparently Acrobat uses Optional Content Groups (OCG), aka Layers, when
creating
watermarks, e.g. via JavaScript function addWatermarkFromText. The
advantage doing so is to be able to switch on and off this layer from
Javascript.
How about OCGs in PDFBox? As far I can see there's no support yet. Is
this on the roadmap? Does anyone succeeded in creating OCGs with PDFB
and is do generous to shar his experience with us?

didn't find it. If it does not (yet) exist could someone please give me
some hints how to implement it?
Thanks, Wulf
