RE: [wsia] Marked up requirements doc from F2F

Title: Message

I think we should at least consider putting a restriction on the 
character set (or, rather, byte range) used for the handle value, as this may 
simplify stuff on the Consumer's part, since if the Consumer is stateless 
it may decide to store the handle in a URL parameter or a form field, and if 
there's a limitation it might not need to encode the state. However, I would 
tend to agree with Rich that specifically regarding the handle, it should be 
treated as an opaque string, and thus even if it is case-insensitive (it might 
very well be so), the Consumer should not be allowed to make this assumption. Is 
there anywhere else where case-sensitivity is an issue?

Let us assume the information in a Handle constitutes a GUID. 
  It constitutes both alpha-numeric characters (again, a Handle is just an 
  example to explain my point - could be any process in the life cycle of a 
  WSIA). The GUID will be higher case and could be lower case - a string in 
  either case should be uniquely same. For e.g.let assume you are passing a 
  parameter "WERTrrr429893484SFGSGGG....", which in a case-insensitive world the 
  parameter has the same value and meaning, and could be different in a 
  case-sensitive world (could even be construed as a totally different parameter 
  by the receving WS application). 

  
There could be numerous other information that are being 
  passed through (at the operational level) - I am not concerned about what is 
  inside the XML/... messages (in the body). The information that is used for 
  processing at a header level in the context of WSIA. 

  
From a WSIA point of view, could this be a requirement?

Are you saying that the value of a Handle must be processed in 
  a case 
insensitive manner? If so, why? Conceptually I 
  view a handle as an opaque 
remote reference. If a 
  Consumer modifies it in any manner (such as changing 
the case), I would view that as a security violation that should cause 
  the 
Producer to refuse access to the referenced 
  item.

All, 

  
I dont know if we had a requirement on case insensitiveness 
  (Upper and 
Lower) of the web services applications? If 
  not, I think we should have one 
under the General 
  Requirements. For e.g., if we are using the information 
in 
the Handle, the Consumer or Producer 
  application should process the 
information in a case 
  in-sensitive manner.

Folks -- here's the marked up requirements document from the 
  face to face. 
Sorry not to get this out sooner...let's 
  get the edits running on the email 
list!
