No, sorry, nothing at all. Even if there were there are *2* parts:
Firstly the relevant language interpreter needs to support whatever
non-marking operation is being executed. In general the language
interpreters do not process non-marking operations (eg the PostScript
interpreter ignores comments).
Secondly the output device needs to support that non-marking operation as well.
In this particular case, while the PDF interpreter ignores embedded files
in a PDF, the PostScript interpreter will pass on /EMBED pdfmark
operations, and the pdfwrite device will process these, which means that
you *can* create a PDF file with embedded files from pdfwrite using
PostScript as an input, but not by using PDF as an input......
