Paul,


it seems that a lot of this discussion has been people talking past each
other, including myself.  I fully support your proposal as stated above.


On the more general issue that seems to have started up this whole thread
of discussion, namely whether a server should be able to suppress certain
attributes due to security restrictions, we seem to mix up general model
issues with security issues.  My take on that problem is the following:


1)  Either the Printer is open (non-secure), in which case the server
should return all the information.


2) Or the Printer is limiting access through some security restrictions,
usually requiring authentication and authorization. In this case, 


a) the client is either accepted and gets all the information, 
b) or it does not pass the security check and does not get anything.  


In consequence, I suggest that there is no half-way house cases where the
server would return some, but not all of the information and we should
amend the model document to reflect this.
