[Kamailio-Devel] Serious regressions in 1.5.0 dialog module - or just me?

Yeah, I know.  I just figured I was missing some of the erudite PV magic

tell whether the parameter in the middle is optional or not via some 
sort of crude scheme.  Your interpretation confirms my suspicion that it 
in fact cannot.
