It probably is :-)

The utility is responsible for generating a PDF snapshot of a view - as
seen by the invoking user at the point when the utility is invoked. To
do this I open an HTMLDOC subprocess which needs a url to go to, and
which needs to know which user to pretend to be so that it can
authenticate... This is indeed all very ugly, but I needed it done and
couldn't think of a better way at the time.

I can't help feeling that to say that a utility should never ever
concern itself with URLs is unnecessarily restrictive.

I sometimes send out an email from an event handler and
getInteraction().participations[0].principal.title is a convenient way
to tell the recipient of the mail who it was that initiated the
change... (from John's post I begin to understand that I might find the
actors details stored in an annotation (if its an annotatable content
object thats been altered))
