Bob,
 
I agree. But the subject was defining some  set  of operations mandatory  for "compliance" with  the standard. The supposed intent would be that, if a entity is "standard compliant",  an interfacing entity can assume some minimum set of support. Although this  is a specious argument in fact (there are very many not-fully compliant implementations of virtually every  standard extant), it is a desirable goal. Because WBMM is being considered for several distinctly different types of application, there should  be  corresponding levels of compliance. It is  unclear if  providing a hard-coded 'not authorized' response  to  unsupported  operations would constitute  compliance.  Or indeed, if it does, whether  "compliance" is  a useful objective.

I can certainly think of "remote" service cases where set and queue management would be appropriate.  IMHO, we should not fundamentally declare in the spec what can and cannot be done over a firewall or across a domain: this is exactly what our authentication scheme should do.  Many customers may not allow set or queue ma agement externally, but many will.
 
As for whether NetSilicon should implement set and/or queue management for proxy solutions, if they are "required" for whatever prile of WBMM you are supporting, you should implement them - but if you are sure that your customers will never allow you to expose them to an external client, you could make them stub implementations that always returned "not authorized".  This would allow you to deliver the solution your customers want without unnecessarily binding other WBMM use cases.

Harry,
 
One of the most immediate  applications of WBMM,  for which no standard  capability  now  exists, is in remote monitoring. In general, any set  operation (and many get operations)  must be disallowed for enterprise security and confidentiality purposes. If one is producing proxy devices  to support  such a capability  (as NetSilicon is), it would  be absurd to require  support of operations that could never be used.  Now, it is not clear  how important  full compliance  to a  PWG spec is, but  if  compliance requires  supporting a whole set of unusable operations, it will become meaningless.
 
I also have  suggested  partitioning this  effort, although not  along the same lines. I think we should encourage more discussion on this, particularly  on  who plans to apply what  part of  this capability  first rather than what appears easier to do first. Indeed, since prototypes  are a necessary  part  of the  standard development, I think getting volunteers to apply these ideas may be the  determining factor  in the  "subsetting" definition and order.

Ouch! disallow SETs? 

I agree (propose) with the concept of subsetting. I am thinking more along the lines of a "growth path"... where we start with Extranet as target and possibly limit our scope to devices, then move to include Intranet and also expand to services, then, finally include queues 

But I think SET capability is needed, even at the lowest compliance level. If not, how, for example, would a remote manager take a device off-line should this be necessary... or post a message to the opPanel?

Harry had brought up  the notion of different classes of compliance in his last minutes. I think this  is as it must go. For WBMM monitoring applications, any  set  operation let alone queue management must be disallowed. But that does not mean that we ought not identify and format set operations.

I do think doing some sub-setting makes sense - in the case of queues, not
all devices/services managed by WBMM will have queues to manage.  

Once we understand the potential subsets, we can talk about which ones need
to be in WBMM 1.0, and which can follow (or potentially be done in parallel.
