RE: D-AC004 D CVX

I like the attempt to retool this goal. 
 
I have raised the point previously that I did not agree with the original goal wording - especially the binding 
between 'platform independence' and 'not precluding programming models' . These seem orthogonal. Also, 
platform independence is already part of the 'consistency' goal (AC011). 
 
I still believe that this goal, AC004, should strip off the reference to platform independence and focus on the 
independent programming model issue. Device independence and this expanded meaning of communication 
modes could also argueably move to the 'consistency' goal too, but I heavily advocate its inclusion somewhere.
 
My preferred phrase for this comes from Roger's below text:
 
"will not assume any particular programming model"
 
and then some examples or possible prograaming modes, for illustrative purposes.

I think that your explanatory addition makes this TONS better.  I still don't really like the "not preclude any programming model" very much, but I can live with it.

Roger,
 
What I was trying to point out was that the current model of web services generally assumes that communicating parties are on-line at the same time.
 
What we want to achieve is that this should not be a limiting factor in web services model. There may be specific web services architecture requirements imposed by devices connected wirelessly and intermittently. So, how about rephrasing D-AC004 to something like this:

ensures platform and device independence of Web Services in a way that does not preclude any programming model nor assume any specific mode of communications so that wireless, intermittently connected, mobile and strongly connected devices are supported

Regards,
Sharad

The following "D" vote refers to: 

ensures platform and device independence of Web Services in a way that does not preclude any programming model nor assume any particular mode of communication between the individual components

I think that saying that we are not going to "assume any particular mode of communication between the individual components" is not well stated and/or not really true.  See D-AR004.3, which says that the architecture will use "XML based techniques ..." (which I think is well stated, incidentally), the charter of the WG and so on.  If there is something really to be said here I think it should be said more accurately.  Otherwise I think that this statement should not be made.

In like spirit, it would seem to me better to say that one will not assume any particular programming model rather than that no programming model will be precluded.  The latter statement is, in my view, asking for trouble since it could be interpreted to include really nasty, stupid or unsafe models.
