Hi Hans,
ConTeXt has a command (\version[...]) to set the version of the document
but as developer there is no way to get access to this value. Can you
give us a defined register which can be used from other modules (e.g.
fixme).
I would even prefer a new command like \setupdocument where you can
set the
document version (passed down to \version), the name and authour
(passed down
to \setupinteraction) etc.
Wolfgang
