Hmm, I'm not quite sure what you are talking about. I just meant that
this profile doesn't do anything more than filling out the signature
field, nothing fancy. No update of visible fields with e.g. signing time
nor inserting a gold shimmering 'seal' icon.
I don't intend to apply any right management functions regarding future
changes of the document. For me the signature is sufficient !
