3.  Review of Action items [.1].  Editorial actions [.2].

PENDING   2004-04-01: Marsh will get schema tf going.
PENDING   2004-09-02: Bijan to create stylesheet to generate a
                      table of components and properties.
PENDING   2004-09-16: Editors to move App C to RDF Mapping spec, 
                      except the frag-id which will move 
                      within media-type reg appendix.
PENDING   2004-09-16: Editors to fix paragraph 6-9 of section 
                      2.1.1 moved into 2.1.2

PENDING   2004-09-30: Arthur to add Z notation to Part 1.

Discussion with Arthur about Z notation and javascript in a single
[pauld: let them eat Z! one version to rule them all..]
Much discussion about how to present the Z notation: inline with
Javascript to hide, 2 documents, etc.
Expectation is to default to Z notation hidden. This would be the
non-normative version.
Normative version would have everything w/ no hiding functionality.

                      vs javascript method later.
PENIDNG   2004-10-14: Editors to add a statement like: 
                      The Style property may constrain both 
                      input and output, however a particular 
                      style may constrain in only one

  e. Good Standing proposal [.3]

Good Standing proposal - JMarsh may have math wrong, but it was an
example of what *would* happen

JMarsh:  Would an Excel spreadsheet be OK?
ACTION:  Marsh to publish spreadsheet with Good Standing calculations.

Concern raised that the Last Call of the spec doesn't match the Primer,

Hugo:    I believe we should point to the editors draft of the spec.
Discussion on how to indicate to readers which documents to use...
[kliu:   ACTION: primer editors to add explanatory text and refer to the
latest editor's copy of the spec]
Arthur:  Concerned about the validation of the primer, not willing to
raise an objection to prevent publishing
Arthur:  The validation of the WSDL in the primer.
[kliu:   ACTION: primer editors to check examples and make sure they are
consistent with the latest wsdl2.0 schema]
Asir: points out a bad link in the primer. DBooth will address
Jmarsh: Any objects to publishing the first draft of the primer?
No objections!
[sanjiva: Thanks to Kevin and David for the hard work on the primer!]
[asir: dbooth, in the informative reference section .. you have a
reference to the primer itself]
[asir: Thanks to David and Kevin, Good Work!]

Hugo sent Email about another problem with our resolution
Hugo:    About the use of out-first patterns with the HTTP binding.  
         At the time we said this was possible, but it would need 
         out-of-band info about where to send it.  With current 
         text, out-first is not very useful. Do we even want to 
         talk about it?
Asir:    We don't have to reopen LC21, we could just take care of 
         implmentation details
Hugo:    Options:
         1. Keep decision we made, allow out-first MEPs. Means 
            Request URI is fixed and in WSDL
         2. Isn't worth it to have out-first, reverse decision and 
            not allow it
         3. We decide we really want it and work out details on how 
            to do it.
Hugo:    Going to be tough to get interop.
[dbooth: TomJ: Not worth having the out-first HTTP. ]
Tomj:    in favor of removing out-first HTTP - save interop grief.
Asir:    supports removing it
Sanjiva: opposed to out-first binding unless it's usable - remove it.
[alewis: agree that out-first is inappropriate for http]
[asir:   I tracked down this particular decision to item 10 in
TomJ:    Don't want to *prevent* people from designing their own 
         way of getting out-first ops to work.
Hugo:    Users can define their own binding.
Jacek:   We talk about this before - it's allowed and anything to 
         make it work is out of scope
Sanjiva: The spec should just talk about the MEPs that work and not 
         preclude others.
Glen:    Extensibility is the way to go here, if someone puts an 
         out-first operation in their WSDL, they better put some sort 
         of indication in the WSDL as to how to get it to work
JMarsh:  Removing it completely (option 1): tools would reject the 
         WSDL unless a (probably mandatory) extension told them 
         how things work
JMarsh:  Reviews the possibilities: remove out-first from HTTP 
         binding, or leave it in and say you must fill in the 
         blanks as to how it works
more discussion on how we could get out-first to work
[asir:   Oh well, we have spent enough time on this !!]
DBooth:  Proposes to change out spec to say that the HTTP binding 
         supports the in-first MEPs. Other MEPs may be used, but 
         would require an extension to be used
[asir:   +1 to Jonathan's rephrase]
Support for Dave's proposal
[GlenD:  Other MEPs may be used, but the semantics of their usage must 
         be defined in some way, such as with an extension or Feature.]
Talking about wording.
[sanjiva: "if some other meps (such as outbound meps) are in use in 
         the interface then some extension may be required to 
         indicate how those work with this binding"]
ACTION:  Part 3 Editors to update the HTTP binding with one of the above
         versions of text

Call next week will be a Task Force. See you next year!
