WS-Enumeration scenarios and test coverage

Here is a note from Nathan Burkhart on WS-Enumeration scenarios and test coverage:

I analyzed the WS-Enumeration scenario tests and the coverage looks good.  All normative statements in the spec are covered.  However, based on changes made and new issues opened during the F2F meeting I think we need to update just one of the tests at http://www.w3.org/2002/ws/ra/test/scenario.html (updates in red below).  Luckily, the changes proposed for issue 12112 are in sync with the test as written.
7.5 MaxTime Test
This test verifies the ability of a data consumer to limit the amount of time it takes for the data source to assemble an EnumerateResponse using the wsen:MaxTime element. The initial Enumerate request has the following salient features:

  *   NewContext element
The second Enumerate request has the following salient features:

  *   EnumerationContext element that was provided by the data source
  *   MaxTime element with a very low value. If a data source is designed such that the MaxTime value will have no impact, for the purposes of testing a data source is to return a wsen:TimesOut fault if the MaxTime value is present with a value less than 5 seconds.
The subsequent Enumerate requests have the following salient features:

  *   EnumerationContext element that was provided by the data source
7.5.1 Sequence

The messaging sequence for this test is identical to that of the Basic Test.
 7.5.2 Success Criteria

  *   Receipt of valid Enumerate message with NewContext element by the data source
  *   Receipt of a valid EnumerateResponse message with EnumerationContext element and with one item by the data consumer
  *   Receipt of one valid Enumerate message with EnumerationContext element and MaxTime element by the data source
  *   Receipt of valid EnumerateResponse message with zero items and with Items/@Reason equal to http://www.w3.org/2002/ws/ra/edcopies/ws-enu/TimedOut by the data consumer

*       Receipt of one or more valid Enumerate messages with EnumerationContext element by the data source

*       Receipt of one or more valid EnumerateResponse messages with one item by the data consumer

*       Receipt of a valid Enumerate message with EnumerationContext element by the data source

*       Receipt of a valid EnumerateResponse message with EndOfSequence element by the data consumer
7.5.3 Conformance
A conforming data consumer MAY NOT be capable of implementing this test due to its inability to support the optional wsen:MaxTime element.
Because this test involves only operations and elements that are required to be supported by the data source, there are no allowable failure cases.
