New {quote:ClassAds} have no concept of private or invisible attributes. This invisibility appears to only be used for dPrint() and some calls to put(). We could modify the put() in new {quote:ClassAds} to take an optional second argument which indicates whether to include the statically-defined list of private attributes. We would also modify dPrint() and/or the unparser class to omit the private attributes. There is also a static method called ClassAdAttributeIsPrivate(), which could become a free-standing function. developer time: 1-2 hours Progress: dPrint() now omits private attributes.
