I might note here that 'manage_changeProperties' already has the
semantics you are looking for;  also, the bug you refer to (about
having to supply unwanted default values for int/float/date properties)
is actually an issue with the ZPublisher marshalling code (the bit
that converts "foo:int" into an int), rather than with propertysheets
per se.
