--------------------------------------------------------------------
4.  FTF planning

Cyclone Commerce in Scottsdale Arizona Jan 20 to 22, tentatively.

--------------------------------------------------------------------
5.  Requirements 

Glen to clarify requirement 116.  Ok to remove abstract vs concrete distinction within requirement 116? Implicit yes.

Requirement R046 Jeffrey Schlimmer  rewording:
  "The description language MUST describe Messages independent from transfer
   encodings." or 
  "The description language MUST describe Messages in terms of the XML
   Infoset."

Glen D. like infoset option. Arthur asked about whether infoset might conflict with provision for alternative type systems. Jonathan Marsh indicated preference for independence of transfer encoding. Discussion seemed to converge on independence of transfer encoding.

ACTION: JeffSch to finish requirements document

--------------------------------------------------------------------
6.  New Issues

ACTION: Jonathan to investigate the first item listed as "new issue" since the link in the agenda seems to be wrong.

Gudge committed to changed "bases" on "portType" to "extends". Amended property name accordingly: wsdl12.xml 

--------------------------------------------------------------------
7.  Importing Schema into WSDL

Defer discussion of include until Sanjiva available.

Jonathan asks Gudge whether xsd:import a problem
Gudge states that we should allow xsd:import as immediate child of wsdl:type. Cf. http://lists.w3.org/Archives/Public/www-ws-desc/2002Oct/0067.html

Don wants best practice on import as an agenda item.
Roberto proposes that xsd:import be treated as extensibility element.
Jonathan states 3 ways to proceed:
  1. built-in,
  2. extensibility,
  3. hybrid
Mixture of mainly 1 or 2 supported.  Arthur like built-in. A. Lewis agrees with Gudge on 1.

Gudge xsd:import under wsdl:type, but treat as extensible. GD questions whether an extensibility item can also be required to implement. Oddity noted, but Roberto says could be done.

Jacek wants us to clean up the wording from "one of element or type attributes", to allow neither to appear (using a qualified attribute to interface with an alternate schema language.)

Jonathan looks for text summarizing this: Describe xsd:import addition, with A Lewis to write text, perhaps with Gudge assist on adding reference in the  wsdl:import section to the xsd:import stuff.

ACTION: Amy to get feedback regarding feature proposal to WG ASAP

ACTION: Gudge and A. Lewis to make a proposal for describing xs:import and  apparently) xs:schema as "required" extensibility elements.

Jonathan has new slice&dice:
  1. Accept xsd:import inside types (Done)
  2. Accept as Built-in (Done) 
  3. Remove in-line completely (Don Mullen champions, we will take up removing in-line schemas completely next time.)

--------------------------------------------------------------------
8.  Identification of a Service

Service identification: defer to when Igor present?  Arthur asks to combine with the more general URI ref proposal when discussed.

--------------------------------------------------------------------
9.  Rationale for dropping the <soap:body use=...> attribute
10. BindingType proposal from Kevin
11. A slice at a proposal for SOAP features/properties in WSDL
12. Issue 2: SOAPAction has been deprecated, as of SOAP 1.2
13. Issue 28: transport='uri'
14. HTTP Binding Issues
15. Issue 25: Interaction between W3C XML Schema and SOAP Data Model 

Did not get to these items.
