     * [11]Summary of Action Items


   pauld: next week is July 4th, does anyone object to meeting?

   omnes: huh?

   pauld: OK, we meet next week as usual :-)

   pauld:if there's interest we could book a table at The Rex cinema
   monday of our F2F:


   planning to publish Last Call Working Draft around next F2F

   would like to not formally meet during August

   planning to work towards an interop event for advanced patterns,
   possibly in Boston during December close to XML 2006

   pauld: presented to WS-I, had some push back, which I blogged:

   discussion around using Relax mapping as a profile

   jonc: little experience or interest in the WG around this approach

   pauld: suggest we ensure Trang generated patterns are covered in our
   Advanced document

ISSUE-12: identifying a conformant schema

   pauld: done nothing on this since we last spoke
   ... suggest task will become easier once we have test cases published

ISSUE-2: WSDL and the Test Suite (Auto-generation of )

   pauld: took exploding sed scripts from Yves and turned them round into
   one stylesheet per target: instance, soap11, soap12, wsdl, schemas
   ... being driven by a single patterns.xml

   yves: suggest using xinclude from xmlspec to include patterns and

   pauld: separated out examples from patterns, associated by links

ISSUE-4: Collection of Databinding Implementations

   pauld: been testing with toolkits, building a list of what we need to
   know to test a toolkit
   .. been working with .NET, Mono, Axis 1.x and SOAP4r toolkits

   wondered about recording this on a wiki so others can easily


   not a big fan of wikis, maybe an issue with access control over pages
   containing licesnes etc

   <scribe> ACTION: ylafon to investigate use of wiki [recorded in

   <trackbot> Created ACTION-50 - Investigate use of wiki [on Yves Lafon
   - due 2006-07-04].

   pauld: alternative is to get people to send mail and just build an
   index from that

ISSUE-34: multiple schemas for a single namespace

   still an open issue in BP, not over yet, WG will solict schema WG's

ISSUE-9: Support for xs:union

   jonc: published a pattern, the Pete Hendry pointed an obvious issue
   with the order of the types
   ... we need to either have more examples, or have separate patterns
   for specific combinations
   ... xsi:type may also play a role here
   ... which way do we go?
   ... with instance documents, should we use xsi:type to test failure

   pauld: is the order of the filters a design consideration?
   ... we can also have more than two simple types, combinations

   jonc: design consideration could spell out what makes sense, could
   duplicate xml schema spec
   ... been using tools to play with combinations, but how exhaustive
   should I be?
   ... maybe we should do some inductive reasoning, just try 2, and 4 or

   pauld: so I'm wondering what we expect tools to do with union "xs:date

   jonc: should we also include anti-pattern instance documents?

   pauld: see no problem in having 'bad' instance documents
   ... just annotate bad documents is important

   discussion of 47! combinations, may be reduced by non-sensible
