Administrivia

   minutes from 30th Jan, 6th Feb, and the F2F approved

   gcowe: we suggested F2F 18-20 April

   pauld: heard a lot of love for the WG at the Workshop last week
   ... challenge is to turn that into participation
   ... maybe we could have an event to promote our work with implementers

   jonc: a day at a F2F, maybe May-June to promote our testsuite sounds
   good

   gcowe: are we ready for that, we need to do more work to be in a
   position to run an event

   pauld: a F2F to prepare our testsuite and documentation might be a
   good way forward
   ... I'd like to get the likes of XFire and WSO2 onto a test report and
   have them compete to be interoperble

   jonc: would that encourage others to participate?
   ... a publicised webinar might get people in and not involve
   commitment on their part

   pauld: a screencast might be an idea, something can run in their own
   home
   ... show checking of a schema using the patterns detection service
   with a toolkit.

   yves: publishing a version of the test report will help a lot - people
   will send comments

Test Suite

   jonc: been looking for missing patterns in BT WSDLs
   ... choice still being throw up as unknown
   ... in particular choice with different cardinalities

   <pauld:> wonders why "we're" using choice, given it's not a basic
   pattern

   pauld: are you making the patterns more generic, or adding more
   patterns?
   ... just tred carefully making the patterns too generic

   gcowe: need to look into this further

   pauld: best to build up with fine grained patterns

Test Report

   yves: been working on the checking of the response XML to request XML
   ... attributeDefault required a specific check
   ... close to having something "good enough"
   ... ready to work on aggregation
   ... verification is based on the example name, e.g integer triggers
   integer comparison

   pauld: working on pattern detection for schemas in the wild

Running the Tests

   pauld: toolkit.xml excludes examples which cause barfing
   ... runit HTTP POSTs instance documents and builds output.xml
   ... as usual I'm the weakest link, and you guys are making me look
   worse, so that's good news :)

   gcowe: so the one service does all the operations?

   pauld: yes

   gcowe: barf-dancing for Axis took an hour and a half with the
   deploy/undeploy step

Last Call Comments

   pauld: still not updated EXIT, sorry!
   ... have had some new comments
   ... philippe asked "is choice a basic pattern"
   ... difficult to tell at present, philippe has offered to help build a
   table at the end of the spec for the use of each schema element
   ... Hugo also commented on the complexity of XPaths, I'll try and tidy
   them up, and write an introduction

   jonc: we've found that some XPaths have to be complex
   ... we've found the XPath reported for "unknowns" isn't always valid

   gcowe: it looks like an XPath, but maybe the stylesheet is breaking
   the lines up and making them invalid?

   pauld: sounds like a bug! I wrote that code, maybe you could send mail
   and I'll fix it

   jonc: a certain toolkit "voldermort" is rejecting our schemas, which
   contain circular references
   ... can we write an XPath to detect that?

   pauld: possibly within a single schema document
   ... or a WSDL
   ... but not with import and include, not easily that is
   ... we have the same issue with inheritance
   ... we could apply an assertion in our basic spec against circular
   dependencies
   ... we need to add assertions to the validation service -for encoding
   etc

   jonc: would circular dependencies and mandatory links is asking for
   trouble
   ... minOccurs="n>0" is asking for trouble

   pauld: raise an issue

   OK we'll meet again in two weeks time

   ADJOURED
