[Bug 6956] Enum: server behavior after end of enumeration context reached

Here is my updated proposal for 6956.  Does this work better for people?
--Geoff




Current Proposal :



section 3.2 (response) be changed to: "MAY generate a

wsen:InvalidEnumerationContext message", and delete the "in any case, they MUST

NOT return a valid PullResponse".





New Refined Proposal:



Changes are in yellow...



[Body]/wsen:Pull/wsen:EnumerationContext



This required element contains the XML data that represents the current enumeration context.



The data source MUST fail the request and MUST generate the wsen:InvalidEnumerationContext fault if the data source is able to determine that the enumeration context is invalid for any reason including:

1.  Context replaced in the response to another Pull request

2.  Context completed (i.e. an EndOfSequence has been returned in a Pull response)

3.  Context released

4.  Context expired



Note that the data source may not be able to determine that an enumeration context is not valid, especially if all of the state associated with the enumeration is kept in the enumeration context and refreshed on every PullResponse.




[Body]/wsen:PullResponse/wsen:EndOfSequence

This optional element indicates that no more elements are available from this enumeration. Additionally, once this element is returned in a Pull response message, subsequent Pull requests using that enumeration context MUST generate a wsen:InvalidEnumerationContext fault message, if the data source is able to determine that the enumeration context is no longer valid.
